Some feedback about the navbar:

1. Multiple codex profiles result in multiple buttons displayed horizontally, this clutters the navbar, specially if there are more than 2 profiles. Best to stick with dropdown
2. Timezone should be moved to the settings page, I don't expect people to switch timezones that often that it becomes a good idea to have a fast switch button on the navbar
3. Same thing for the password, already supported in the settings page
4. There are 3 buttons for layout options, I don't notice a big difference on my MacBook or my iPhone, not sure if it's useful for other layouts but maybe move it to the settings as well?

These 4 alone would greatly simplify the navbar.

Other points about UI/UX in general:

5. "Dashboard - Track your Codex API quota usage in real time." this doesn't provide anything useful but takes vertical space. I notice patterns like this a lot with UIs built by Codex, Claude is usually much better at these things
6. I don't remember the exact wording now but when usage is above the desired pace, the wording is opposite of what it should be (eg. it says we are x% in deficit instead of x% in excess, or something similar)

Other misc:

7. SMTP test always fails for me with wrong credentials but I have emails working fine (I received many times)
8. Also never got push notifications to work. No idea how it works. I'm using Safari on macOS, my app is deployed on a NAS with Traefik as reverse proxy and my own domain (onwatch.mydomain.com), not sure if it helps in any way, as I believe I saw somewhere that it requires HTTPS which I'm using
9. Would be nice to have even more control about notifications. For example, I'm often restricted about weekly limits but not by 5-hour limit. I want notifications of resets for the weekly (specially because of random resets by Codex team) but I don't want to be notified every 5 hours by that limit reset
