That's the thing though with well developed apps:
I think I also dislike the new icons. But it doesn't really matter, since the old ones are still there and I can continue using them..
The dark mode seems a bit buggy still and the contrast really is to stark, but I am hopeful these problems will be addressed with time.
Not everything is always right at the beginning, but I am never afraid to update notepad++, which is a huge compliment these days.
