i switched to using neovim a year ago and oddly enough its actually a lot easier to write code in termux compared to any of the other android IDE type apps. they all have drop down menus or sidebars that are quite awkward to use, especially when the keyboard is already taking up half the screen, but with neovim (or vim) youre using the keyboard to do most things anyway, so the keyboard can just stay open all of the time and you never need to move your hand up to the actual app part. selecting text is way easier than android's implementation as well
