Motivation and Context

I wanted to have the UI looking more after Unitys Dark Theme, cause I find it very appealing and minimalistic.
On top of that I think it is good to give users coming from Unity the opportunity to recognize UI-Elememts faster and feel "home".

Despite the new Theme I have found some small UI bugs and spotted here and there possibilities to improve the look a little bit.

Further I have read some comments in Discord, that some people have problems recognizing the Gridseperator in the Property Grid, so I have made it visible,
to better communicate the possibility of dragging it.

Due to the planned switch to avalonia, I have only changed small things, to not waste too much time on that.

if you are still working on it you could add WIP to the title so its blocked for merging

[tebjan]

If it is WIP the correct way to make that is by pressing "convert to draft":

I think @Eideren was trying to get confirmation on why this was made this way. Depending on the time needed to wait for confirmation I think this PR is good as is.

I want this to be merged so I can use it lol

[Eideren]

I think we can merge it while D3ZAX gets back to me, is this PR ready @SVNMLR ?
