For general use I'd like to add multitail (logging done wonderfully right), canto-rss (RSS reader/server), ncTelegram (Telegram client), turses (Twitter client), centerim (multi protocol IM client), weechat (IRC) and iftop (traffic monitoring for me), alpine (mail client) and mc (file manager). At least they're the tools termux starts with on my VPS and I pretty much live on there.
