I don't need support for dropbox.
I don't need support for "sharing". The text editor is allowed No Internet Access Whatsoever.
I already have a file browser. I don't need another one.
I don't want or need text formatting, i.e. bold, italic, font family and size changes. Syntax highlighting, I could deal with.
It absolutely baffles me that such a text editor should be so hard to find, but for the life of me, I can not find one with this feature set. All I want is to open, edit, and create new text files from my file browser. (My file browser does not come with an integrated text editor for exactly the same reasons I don't want a text editor with an integrated file browser. I will not migrate from my file browser. It's the default file browser in LineageOS in case you're wondering.)
