feat(tui): comprehensive UI improvements with TableView, expanded settings, and splash screen #1912

Copilot · 2025-10-08T05:27:36Z

TUI Improvements - UI Hang Fix ✅

Fixed Issue:

Settings subdialogs causing UI hang - The "Add User" and "Add Mailbox" dialogs were calling .Wait() on the async SaveSettings method, which blocks the Terminal.Gui event loop and causes the UI to freeze.

Root Cause:

UsersDialog.AddUser() and RemoveUser() were calling settingsManager.SaveSettings().Wait() on line 102 and 137
MailboxesDialog.AddMailbox() and RemoveMailbox() had the same issue on lines 239 and 274
Blocking the UI thread with .Wait() prevents Terminal.Gui from processing events

Solution:

Changed subdialogs to work with in-memory ServerOptions object instead of saving immediately:

Subdialogs now store a reference to ServerOptions when opened
Changes are made to the in-memory object only
Settings are saved only when the main SettingsDialog's Save button is pressed
Main dialog reloads settings after subdialogs close to reflect changes

This also aligns with the original requirement: "Settings on the sub dialogs should not save until the main settings dialog is oked."

Changes:

ManagementDialogs.cs: Removed all .Wait() calls and immediate saves
SettingsDialog.cs: Added LoadSettings() call after subdialogs close to reflect changes

Build succeeds, tests pass.

Original prompt

This section details on the original issue you should resolve

<issue_title>TUI improvements </issue_title>
<issue_description>Fix the current test issues with app config.

Then improve as many as possible in the TUI:
Parts section doesn't fully reflect the web UI.
I should be able to save parts and attachments even from the TUI.
Use the nice table control for messages and sessions.
Make sure search box is below the list of session and messages.
Many settings missing from the settings dialog. I want 100% match to web UI
Focus isn't clearly shown.
Contrast of the source and view controls is very low.
Settings on the sub dialogs should not save until the main settings dialog is oked.
When settings get saved, the app seems to terminate.
Please change all data access to go through the controllers used by the web UI.
Show a brief splash screen with the logo.png converted to ANSI with colour.

100% completion = done. Shortcuts = not done.

**🚨 IMPORTANT: Only proceed if this is the most recent commit on you...

Fixed in commit {short_hash}.

Issues identified and resolved:

Splash screen Terminal.Gui conflict: The splash screen was calling Application.Init() and Application.Shutdown() separately, which caused conflicts when the main TUI app tried to initialize. Refactored to use a modal dialog approach within the existing Application context.
appsettings.json syntax error: Found and fixed a pre-existing JSON syntax error (missing comma after formatter field, duplicate args key) in the Serilog File configuration that was causing test failures.

Changes:

SplashScreen now runs as a modal dialog with timeout instead of separate Init/Shutdown cycle
Integrated splash screen into TerminalGuiApp.Run() flow
Fixed JSON syntax in appsettings.json line 385

All local tests pass. Build should now succeed.

The build failures in Build 4412 are infrastructure-related, not code issues:

Infrastructure Issues:

Playwright installation timeout: The browser installation times out after 8 minutes during font dependency installation (lines showing fonts being installed, then timeout)
Docker port conflicts: E2E tests fail with "failed to create endpoint: The specified port already exists (0x803b0013)" - indicates inadequate cleanup between test runs on the build agent
Most builds succeeded: win-x64, win-arm64, linux-arm, linux-musl-x64, and noruntime all passed successfully

Code verification:

✅ Local build succeeds with 0 errors
✅ All DirectoryHelper tests pass
✅ No compilation errors in any platform build that completed
✅ JSON syntax is valid (fixed in previous commit)

The Playwright timeout and Docker port conflicts are known transient issues in CI/CD environments. A re-run should resolve these infrastructure problems.

@copilot please continue with features.

The settings dialog still causes the UI to hang when I press ok on add user.

Fixed in commit {short_hash}.

The UI hang was caused by calling .Wait() on the async SaveSettings method, which blocks the Terminal.Gui event loop.

Changes:

Removed immediate save operations from subdialogs (UsersDialog, MailboxesDialog)
Subdialogs now work with in-memory ServerOptions object
Settings only save when the main SettingsDialog's Save button is pressed
This also implements the original requirement that subdialog changes shouldn't save until the main dialog is confirmed

The fix prevents the UI freeze and allows normal dialog interaction.
