My personal suggestions for UI

[waheedullahkhan001]

1. The initial splash screen's progress bar should be a bit smaller.
   Something along those lines?
   
2. The launcher itself is missing some subtle details which impact its look and feel. For instance there is lack of separators/outlines that indicate separation between components.
3. Add some spacing. The UI isn't really that bad it's just that is too crowded.
4. The buttons which are not highlighted should look normal but they look like they are disabled because the text color is way too dark. This is also the case with some other text in the UI. i.e. the column headings (in server list)

That would be the most of issues. I would say the most important ones are spacing and outlines.

I am no expert in this field but I tried my best to pin point the issues.
