Similar story here. Used to write my python codes in subl till I finally jumped ship to PyCharm.

But I didn't stop using Sublime. I set a keyboard shortcut to launch it, and thankfully it doesn't open multiple instances if already running but pops up on foreground. And now it's my scratchpad, a temporary clipboard, a distraction free zippy screen where I compose my messages before mailing them. And its probably my most used application, lately.
