If someone wants to do easy things for the Android port, they would be: - make dired.c understand the `/assets' special directory. - make drawing faster by avoiding the extra canvas save and restore on each graphics op, only doing that if clip rectangles really change. - add support for touch screen events, like in xterm.c, and the on-screen keyboard. - add support for the TrueType Container format to sfnt.c and sfntfont.c. This is easy because TTC files are just TrueType files with multiple table directories, each representing a single font. - add support for window restacking and geometry operations (i.e. raise-frame, android_reparent_window, et cetera.)
