I've used gedit, but I'm not familiar with multi-cursor implementation in it. I suppose I've always seen the multi-cursor implementation in Sublime Text as top-notch with other editors struggling to implement anything like it. Intellij finally has pretty decent multi-cursor support but it's still a little bit behind ST's. For example, in IntelliJ the ease of applying multiple cursors seems to involve more work than in ST. In VS Code multiple cursors isn't nearly well implemented as ST or even IntelliJ.
