feat: allow for faster turn-round times when developing the ui

[mvrueden]

This change allow for faster ui development with some quirks while doing so.

However, I think the tradeoff is bearable, especially as this is the way modern applications are meant to be developed.

Cheers

LGTM.

[synqotik]

Thanks for doing this, I meant to but didn't get around to it, though due to how the menu works there are some issues (which you noted).
