This is a question of adapting to higher resolution screens. We have (who complains) 480 x 800.
At the author Optimus One - 320 x 480. On this screen it looks fine (checked with my wife) :-)
But even tablets exist from 1024 to 600 and beyond.
In general, adaptation for all screens is a big and difficult job.
Below are such small icons of something that just did not understand.
These are category icons - movies, series, etc. They are located to the left of the name of the transfer.
Identifying them is really difficult.
As I understand it, the icons are based on categories with mail.
There is an offer to think over color gradation
pantsof icons. If films for example are marked with an icon in blue shades, serials in green, news in red, etc., in my opinion, this will greatly add to their recognition - recognizability. If the author likes the idea, he is ready to help (if necessary) with drawing icons.
