Multi-cursor mode
In some other editors (at least Atom) you can have multiple cursors (with Ctrl+click, or Ctrl+Shift+↓, and when you type something, text is inserted under both of them. It is really useful when you have to perform many times the same modification on various lines.
I feel like this would require massive reworking of how GtkSourceView worked, but I agree if it were possible it's an awesome feature from other editors like Atom, VS Code, and Sublime.
Note that gnome-builder which is also based on GtkSourceView already supports multiple cursors. There is also an open bugreport on GtkSourceView for multi-cursor.
@drequivalent any news on this would show up in the timeline here, whether it was someone commenting on this issue or a PR that was working on it.
Marking this as dependent on upstream developments as I can't see us having the resources for making the significant changes to Gtk.TextBuffer/Gtk.SourceView required
