hey vortex. thanks for your great work. although there are a few issues that makes the build not daily usable for me.
1. the default power button does not lock the screen and touch interface on short press, like stock or all smartphones do. i have to long press power button in order to lock it. which is not intuitive.
2. usb file transfer does not work. i dont know if it's my issue, but i have to latest build. i have to get a usb card reader for it in order to upgrade system or doing file managements.
3. the default theme doest not support asian characters. im a veteran rockbox user i know how to fix it very well, but you should make fixed font default.
4. fast foward and fast backward is buggy and slow and sometimes dont work.
also things that are not limited to m3k, but rockbox in general.
1. support dual section display: aka make wps in the same screen of tree menu. vortex's m3k build incorporated an element like this, but limited only artist, title, no time and other infos.
2. support dual line menu item. aka make the menu item with long names wrap into second line. but second line only, if it's too long, still rolls like single line. this way could make higher res / high dpi screens more useful without result to small fonts. which is not user friendly.
im planning making my own theme for m3k (probably other devices with 240*320 screens too). it would be a minimalistic (light grey text on black backdrop, no album art), larger font (20+ font size) with unicode support.
