That’s one of those requests like: Could you fly me to the moon and then bring me a cold beer from Mars? Please 
But still, could you imagine something like smart folders that automatically generate a list, a floating menu, or something similar, based on certain criteria, where BTT triggers are listed?
So I could say, “Show me all key sequences from CAG X ans Y.” Or “Show me all triggers from Safari that have the word ‘window’ in the title.” Or … you get the idea.
Many apps use “smart folders,” (even the Finder) which let you group together things that otherwise could hardly be displayed at the same time. That’s definitely handy.
Maybe something like that could be done with the Launcher? It can do almost anything these days, can’t it?
