@BeAware Being on Mastodon / Fedi for almost a year now, it actually took me a while to understand how hashtags are used. Whereas on other platforms they're used more expressively as content keywords - here, they tend to have very specific meanings and used more for organizing / filtering. That means that random tags have no purpose, and most people commonly use a set of specific tags. So, with that, yes, I like your idea. Perhaps a tabbed dropdown, like the emoji one, to select common tags.
