If you're an everyday sort of computer user, and need to collaborate with other members of the council, I might recommend using Google Docs, and Google Calendar. They each have collaborative features. You can collaborate with Abiword, too, but Google Docs is probably preferable there.
If you just need to multitask and text edit quickly and efficiently on Android all by yourself, and are a programmer-type person, I recommend using
Termux, with the Nano text editor with a bluetooth keyboard.
Termux is a command-line Linux that you can install on Android (it's just an app; it doesn't replace Android with Termux).
Nano is a command-line text editor for Linux.
These all have a learning curve. I recommend learning how they work before you do anything too serious.
