Before submitting

• I searched existing issues and did not find a duplicate.
• I included enough detail to reproduce or investigate the problem.

Area : apps/desktop

Not sure if this is being worked on. Will close the ticket if it gets fixed in any of the releases.

I have a fix but not sure if it's the best fix so haven't raised a PR.

Steps to reproduce

1. Start the desktop app with the latest version (0.0.15)
2. Resize the window till the sidebar is collapsed

Expected behavior

In the Electron app on macOS, header content should be positioned so it does not overlap the native window controls. The active thread header, empty-state header, and settings header should remain fully visible and usable at all window sizes, with proper spacing reserved for the window buttons.

Actual behavior

macOS traffic-light controls overlap chat and settings headers in Electron

Impact

Cosmetic issue

how are you hiding the sidebar in desktop mode? that's not supposed to be supported

[frittlechasm]

Just resizing the desktop window auto-hides the sidebar ( video below )

Hmm what mac is this? You shouldn't be able to make it that small

Edit: oh if you have different scalinh it collapses sooner. Got it

[frittlechasm]

Didn't realise i was zoomed in.
Yes, going to default does prevent me from resizing the window to where the sidebar would collapse.

If it's intentional to not collapse the sidebar on desktop should i close this issue ?

[juliusmarminge]

Nah we should fix it. Lots of people will use a zoomed in view and it shouldn't break because of it.

So we need to apply the padding to the "mobile header" if isElectron && isMacPlatform()

[frittlechasm]

If this works and it looks okay I can raise a PR : frittlechasm@ba3c2a7.

I couldn't find a specific "Mobile Header" in the codebase.
If something is in the roadmap and planned i am happy to wait.

Another small issue if we are supporting this :
On a fresh new open when you see a "No active thread" header and the sidebar is collapsed there's no sidebar-trigger icon

No Sidebar Icon:

Sidebar Icon present:
