If you could create "composer actions" that modify a cast before it's posted,  what would you build? Potential capabilities: change or prefill text, add media, add frames.

there is so much emphasis on "building" regarding casting. how do you even get your casts seen? why would i want to do all this if i cant even get 3   likes on post. does a PB help? how do you get one? i have more followers than some that have one, lmao. should we be casting in channels for more exposure? emphasis seems to be on PB users but how do you even get one? i have asked multiple times
