As the Gemini's strength is its text editing, one of the things I expected to do a lot would be to either grab text from another machine and edit it, or just create the text on the Gemini and send it somewhere else. But I've completely failed to find any decent file-transfer app for Android! I thought at least there'd be ftp. I found one "Send to FTP", but its UI is terrible, so I dumped it again. NitroShare also looked good, but when I installed it on the Gemini and my laptop (Mint), the two completely fail to communicate. (I've added an issue on its Github page, so maybe it could be solved.)
Of course I have termux, which has FTP, but the command-line is not the most convenient interface here!
Does anyone know of something more useful?
