I think its better to checkout in the branch and check the changes
Keeps themes better into account

I think these hover things should be the same. I think everything that is inconsistent kind of takes me out of focus.

No hover transitions. What kind of button is the open in studio button?

This one has no hover so it is inconsistent

Hovering over active nav button should not change

This is a pretty good example of how different buttons act very different. I'm not saying there shouldn't be different buttons, but they should feel coherent.
We need to look at all different "types" of buttons and create components for them, and use them consistently.

Transition

This is not the button component?

Dropdowns:

(that one should be combo box honestly)

I'm not sure if I got to see everything with my current setup. Overall there is still a lot that can get cleaned up.

@philipsens Perhaps its a good idea to go through the application one more time together to find inconsistencies?

[philipsens]

Sure!
