The most noticeable problems were fixed in 0.5.2. Work continues...

TODO:

• fix white text: https://www.openstreetmap.org/way/499695465/history
• settings menu
• Dark theme for iD (only a white flash remains when opened)

The settings window should be updated as well

I would completely redo it, there are a lot of settings there and the design is from the 2000s)

The settings menu has been fixed.

Guys, what do you think about the diffs colors in the dark theme?

Now the option in the middle is used, but it bothers me that it is rather whitish. I've been using the first option for a few days and I like to use it with an inverted map. What do you think?

upd: Hell, colors are hard. I connected the monitor and they are already different :\

I definitely prefer the last option with more saturation. Btw I use the map without any filter but still dark UI.
