The key of having an awsome app is having great features (as solid explorer) and having great UI (that's the Solid's problem).
UI of Solid explorer 2 is very bad, icons are as same color as top bar, drawer icons are not beautiful, rounded icons in drawer are the worst, current Solid's UI is not well, it gives me a very bad feeling and it bothers my eyes a lot, pls pls pls change these, I know very people will be glad, I love this app but I care so much about UI, this UI that solid explorer need to be changed.
the Cabinet Beta (screenshots) is a greaaat app in UI, but it has so many bugs and its features are very simple. pls change UI, it bother eyes and makes bad feelings about this great app.
One more thing; I love ES File manager feature that when I want to install an application, it shows current version that I installed and the version that I'm going to install, its very helpful.
