Where Vim Came From
For some reason i'm not the biggest fan of vim on a computer. But, vim on android with termux is the best editor i've found for android and I don't know why but as weird as it may seem using vim with the right touchscreen keyboard isn't actually that bad. It's the only realy solution i've found for doing small amounts of programming on my phone. Nothing big, but for small hundred line or so, scripts and such vim is definitely the best thing i've found to use on android.
