In my (personal) opinion Gemini 5 waste too much space on the page. e.g. when creating a new issue then half of fields we want to fill is out of the screen. I would like to tweak the UI using the themes to have more space for fields. During tweaking I encountered folowing two issues:

1. I cannot change the theme in Preferences. It allways resets theme to "default". I already mentioned it in another question but no answer. I also tried to create another theme (copy the content of the default directory to the new one) and/or change it via database, but it doesn't help. Is it a bug? Is there a trick how to do that?
2. OK. I tried to edit the default theme. But after some time playing with it I realized that changes doesn't affect. It is because Gemini uses packed version of CSS theme (all.min.css). So my question is: How we can edit the theme?

Your support is very appreciated.
