## Git History
|
|
|
|
```bash
|
|
# TASK-007A/B/C merged to cline-dev from feature/task-007-integrated-backend
|
|
# TASK-007D merged to cline-dev from feature/task-007d-launcher-ui
|
|
```
|
|
|
|
## Testing Notes
|
|
|
|
The UI components use IPC handlers registered in main.js. To test:
|
|
|
|
1. Run `npm run dev`
|
|
2. Open Backend Services panel
|
|
3. Create a local backend (name it)
|
|
4. Start/Stop the backend
|
|
5. Check the displayed endpoint when running
