Changes regarding the stock version:
1. corrected translation (Russian and English (I did what I could)),
2. replaced the font with a new one from XVortex,
3. customized both themes (some pictures, icons, their locations, etc. were replaced), increased font size in some places. Main screen in second theme is based on the Hexagon theme from Steven Van Geert (see FB HiBy topic),
4. repaired choosing colors sliders in the second theme,
5. added a stepcounter to the side menu,
6. added adb (it's really useful and working properly),
7. replaced the index page when connected to PC via Wi-Fi (now always in English), plus changed sort order (folders go first, then files, in order of names: at the beginning the numbers, then Latin, then Russian) and following file formats have been added: upt, txt, log, and t,
8. added a radio to the top bar and replaced the built-in radio stations with my own (40 stations), others you can persanally add to
radio.txt file and put it in the root of your sd card,
9. all binary files have been striped,
10. optimized all *png files,
11. removed unnecessary files and folders that are not used,
12. extend database limit to 40000.
The limit I've found in hiby_player binary of course with Hex editor:
20 4E (4E 20 = 20000 in dec.), so I changed it to
40 9C (9C 40 = 40000 in dec.). You really need to know this?
