So, here’s a crazy idea.
Usually I would have multiple tabs opening in sublime and when I want to change the same thing in more than one file, I would have to do it in the individual file.
Currently the multi-select/edit is doable in the active tab only but it would be really useful if I could do it in more than just the active file.
It’s super crazy I know, but it would make editing multiple files a breeze.

A basic workaround right now might be a find and replace across all files using the the inbuilt Ctrl+Shift+F shortcut in Sublime Text. You can use regular expression to define the search text.
