Navigation:
- Tab: Switch hosts
- ↑↓/jk: Select service (always works)
- R: Rebuild host
- s: Start service
- S: Stop service
- q: Quit
The interface is now much simpler and more intuitive with direct service control.
Simplified keyboard controls by removing service restart functionality:
- Removed 'r' key restart functionality from Services panel
- Made 'R' key always trigger system rebuild regardless of focused panel
- Updated context shortcuts to show 'R: Rebuild Host' globally
- Removed all ServiceRestart enum variants and associated code:
- UiCommand::ServiceRestart
- CommandType::ServiceRestart
- ServiceAction::Restart
- Cleaned up pending transition logic to only handle Start/Stop commands
The 'R' key now consistently rebuilds the current host from any panel,
while 's' and 'S' continue to handle service start/stop in Services panel.
Resolved issues with transitional service icons not being properly visible:
- Removed 3-second timeout that was clearing pending transitions prematurely
- Fixed selection highlighting disappearing when transitional icons appeared
- Implemented conditional coloring for transitional icons:
- Blue when service is not selected
- Dark background color when service is selected (for visibility against blue selection)
- Transitions now persist until actual service status changes occur
Both selection highlighting and transitional icons are now visible simultaneously.
The root cause of transitional service icons not showing was that service names
were stored as raw names (e.g., "sshd") in pending_transitions but looked up
against formatted display lines (e.g., "sshd active 1M ").
Changes:
- Modified display_lines structure to include both formatted text and raw service names

If arrow appears: pending transitions logic issue
If no arrow: basic rendering path issue

- Add 3-second timeout for redundant command visual feedback
- Include timestamp in pending transitions to enable timeout clearing
- Show directional arrows immediately regardless of command validation result
- Fix core issue where state validation prevented visual feedback storage
Now pressing s/S/r always shows immediate directional arrows, even for
redundant operations, providing consistent visual feedback to users.
- Prevent selection highlighting when service has pending transition
- Allow directional arrows (↑ ↓ ↻) to show through on selected services
- Fix core issue where selection styling was overwriting transitional icons

The selection highlighting logic now skips services with pending transitions,
ensuring that directional arrows are visible when executing service commands.
- Replace timeout-based command status with pending service transitions
- Show immediate directional arrows when pressing service commands (↑ ↓ ↻)
- Track original service status and command type for each pending operation
- Automatically clear transitional icons when real status updates arrive
- Remove unused TerminalPopup and CommandStatus infrastructure
- Simplify visual feedback system using state-based approach
Service commands now provide instant visual feedback that persists until
the actual service state changes, eliminating timing issues and improving UX.

- Prevent redundant operations (start active services, stop inactive services)
- Show immediate directional arrows for command feedback (↑ starting, ↓ stopping, ↻ restarting)
