Another features / sugesstions from me
1. Let us fastly switch between search- and replace-dialogs: Have a look to attached examples, here: red marked on bottom-left.
By searching-dialog, you can switch to "replace", and in replacing-dialog, you can switch to search. Its a feature of Top-Style CSS-Editor, which is not longer supportet.
2. In same dialogs:
Clicking / entering in a field of (these) dialog-boxes, the content could be selected /mark it in same moment. Maybe this option could bei an option in programm-settings.
Thanks and bye,
