I buy mostly nothing, use ms alternatives like libre office, blender, gimp, resolve, darktable, etc, but sublime text has been a fantastic lightweight ide, like a notepad++ or gedit. Even when other big companies are coming out with nice free smaller than before apps, I'm happy to have bought sublime. I find I can use many editors at the same time for different uses to separate my minutia.
Version 4 accepted my version 3 license purchased in january 2019. Yay me!
Yes accepts a max 3 year old v3 license. Mine is 8 and been worth it, just not another 70$ now that I’m force learning myself vi :-) 3 will remain fine for the quick things I want it to do
