Add a connection-management feature to YAMA: a toolbar button (after MCP)
opens a dialog listing the managed host's TCP/UDP connections, with
right-click force-disconnect for IPv4 TCP rows.
Client: a new CConnectionsManager enumerates connections via iphlpapi
(GetExtendedTcpTable/GetExtendedUdpTable, IPv4+IPv6) and answers the
refresh and kill commands over a sub-connection.
Server: a new CConnectionsDlg (DialogBase) shows the list with sortable
columns and a right-click menu; the title-bar icon reuses the toolbar's
connection icon (res/connections.ico).
Fix byte order found during review: iphlpapi returns an IPv4 address as a
network-order DWORD and the port's low 16 bits in network order, so
storing them raw made the dialog show reversed IPv4 addresses and ports.
The client now stores addresses as network-order bytes and ports as host
order (ntohs), and reverses the conversion on disconnect.

Add a novice-friendly "File Transfer Speed" dialog under the Advanced menu
that controls file-transfer speed in both directions without touching
SimplePlugins. Speed is passed through InitFileUpload's existing
chunkSizeKb/sendDurationMs arguments, so the precompiled library stays
untouched. Seven presets run from ~0.3 MB/s up to a new 10 MB/s tier plus an
unlimited tier; the chosen value is stored in [transfer] ChunkKb/DurationMs.
Upload reads THIS_CFG at the master's InitFileUpload (2015RemoteDlg.cpp:2225)
and takes effect on restart. Download is pushed to the client over a new
CMD_FILE_SPEED (252) command, sent from OnOnlineFileManager and
OnOnlineDesktopManager before each session opens, and read by all four client
InitFileUpload call sites via GetTransferSpeed so the process-global refcount
cannot latch a stale speed. All Chinese strings go through LangManager, with
en_US/zh_TW/de_DE entries added for the tier names, format strings and hint
text.

Add a dedicated ShareHostDlg with a "Use Shine protocol" checkbox (default
checked) so the operator can choose Shine (0) or HELL (1) when sharing or
transferring a host. The chosen protocol is appended to the wire payload as a
trailing colon field: "IP:PORT:0/1" for share and "IP:PORT:days:0/1" for
transfer.
The client parses the trailing field from COMMAND_SHARE and
COMMAND_ASSIGN_MASTER, applies it to new connections, and persists it so
auto-share/auto-transfer on restart keeps the same protocol. Old clients
ignore the extra field, and old/missing payloads fall back to -1 (baked-in
HELL), preserving compatibility with existing servers and share_list entries.

Implement the P2 upload_file tool to push a local file or directory from the
master to an online Windows host over the existing V2 file-transfer protocol.
The server drives FileBatchTransferWorkerV2 synchronously on the main
connection through a headless callback, reuses the list_files chain for the
overwrite pre-check, and is gated by McpFileTransfer=1 plus McpReadonly=0.
The client main connection never initialized the file-transfer module, so
g_status stayed 0 and RecvFileChunkV2 silently dropped every chunk, truncating
uploads to zero bytes. Add a once-per-process lazy InitFileUpload in the
COMMAND_SEND_FILE_V2 handler that mirrors the FileManager init; the destructor
deliberately does not Uninit so g_status remains 1 across reconnects.
Update the design doc to record the client-side change and correct the
upload_file description to state that sha256 is not returned (V2 has no
receiver-to-sender ACK; integrity is checked client-side and logged only).

Record the client's active-window history (start time, window title, and
dwell duration), newest first, skipping dwellings under 5 seconds and
breaking the timing on idle, capped at 500 entries. Add an "Activity
History" item inside the host's Client Management submenu that requests
the snapshot over the main connection and shows it in a new dialog. The
dialog rebuilds its edit control as a Unicode window so UTF-8 titles
render correctly instead of degrading to "?" through the MBCS ANSI
boundary. The menu item and dialog title go through _TR and are
localized in en_US and zh_TW.

Server sends COMMAND_SCREEN_PREVIEW_REQ when user double-clicks an
active (non-Locked/Inactive) host that advertises CLIENT_CAP_SCREEN_PREVIEW.
Client BitBlts primary screen, encodes to JPEG via GDI+ and replies. The
existing STATIC tooltip is replaced with a self-drawn CPreviewTipWnd
showing the thumbnail above the host info text, with wide-character
rendering so the popup also works on non-Chinese servers.
- Quality tiers reuse QualityProfile pattern: PreviewProfile + 6 levels
driven by GetTargetQualityLevel (FRP-aware), with 4K/ultrawide auto
upscale on Ultra/High tiers up to min(screenWidth/4, 1280).
- Client limits to 1 in-flight capture via atomic counter to defend
against flood/DoS; Send2Server is already mutex-serialized.
- Server validates responses by reqId only (single in-flight tip);
4s arrival timeout marks "preview unavailable" without blocking the
text fallback path.

Client first packet on every sub-connection signs (clientID || timestamp ||
nonce) and waits for server ack. Server verifies signature and pins clientID
on the sub-connection ctx, eliminating IP-reverse-lookup unreliability for
NAT/localhost scenarios. Sub-conn coverage: Win 12 sites, Linux/macOS 3-4
each. Main connection keeps existing TOKEN_LOGIN flow unchanged.
Includes:
- Protocol structs sized to 512/256 bytes with reserved space for future
extensions (locale, OS info, session token, etc.)
- 5-min timestamp tolerance (Kerberos-grade replay window)
- 10-sec client wait for cross-pacific / weak-network tolerance
- Fix RemoveFromHostList side-effect ordering: MarkDeviceOffline and
m_ActiveWndW.erase now only fire when ctx is actually removed from
m_HostList, preventing sub-conn disconnects from misreporting main as
offline (regression introduced by auth-set clientID on sub ctx)
- Fix latent bug: IOCPClient::m_conn was never assigned in ctor, leaving
GetConnectionAddress() always NULL and FileManager V2 transfer's
srcClientID always 0
Breaking change: new client cannot use sub-features against old server.
New server tolerates legacy clients (no auth). Future tightening can reject
unauthenticated sub-connections via IsAuthenticated() flag.
