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.

gif search killer app in the works with this prob can it be multi step? -> input text (brings frame with searched input possible gifs) choose one -> updates with that media without frame (i hate gifs in frame as is witth regular cast action implementations).
also could we get links to gifs to hide the default card and just show the gif in general? would make gif usage here easier for those who cant upload like android users idk

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

What does this mean in practical examples?

Suggest best channel to post this in - based on past casts by me.
