Hi, I have been using Termux for quite a while on my Android & must say that its my favourite terminal emulator for Android.... There's an SSH app I use called JuiceSSH which gave me this idea, plus when a command doesn't execute properly & it hangs I cannot stop the hanging, nor can I even make termux exit, which forces me to reboot my phone because termux creates a notification that I can't make close...
I have to type exit in order to get termux to exit, that's not good, perhaps you guys could make it so we can close the app from outside of the app?? A feature to change the text colour would also be cool, it would be easier to read the text if it were bright-ish green on a black background for example.
arrow keys would also be a huge help, that way we can cycle through previous commands, its kind of annoying having to re-type the same command on a touch-screen.

This is what JuiceSSH's looks somewhat like:

You can hide that extra menu above the keyboard quite easily too.
