Wanted to title What kind of tool would you be very interested in for training but it limits to a ridiculously small amount of characters...

Anyhow I don't know what there is these days I used to mess around with a few things like multitasking trainer and green tea AI I'd like to make an SC2 programming project cause its so interesting I love this game was obsessed with it ever since I discovered it in 2010 as my brother surprisingly wanted it as a birthday gift even though he was never into RTS but he loved WoW another blizzard game. I found SC2 to be even more addicting than WoW was which is crazy... I reached low GM mmr in 2015 and since I'm so familiar with the game thought it'd be a great project to work on...

So, is there anything unmade that you'd love to have as a training tool or something that you need a better version of? I'm up for a challenge...
