If anyone has created an action to post messages to Slack, I'd love to have a look. Something along the lines of:
1. launch action, spacebar
2. select @person, #channel, or #group by typing in name, spacebar
3. type message
3.1 typing ":" brings up the slack emoji menu (like in the app).
I have no idea if this is difficult, or even possible, but if someone uses slack at work, I'm sure they'd find it super-handy
