Feature request: sorting, categories

Hello, can you add the ability for one to sort the titles of the regexes alphabetically? Could you also maybe add a tagging and/or folder feature to sort into categories? Thank you

Response from developer

Yes, will do. Thank you for your feedback.

Good basics, lacks replace versatility

The app has all the basic functionality I needed. presets, find/replace. The text highlight is very basic, wish it was multiple colors, so i can see exactly what regex is selecting.
Also I can’t type linebreak “\n” and other escape characters in ‘replace’. The workaround for now is to select (\n) in find and then put it back with $1. Maybe there are solutions for that, but it’d be nice to have by default.

Very bad

I want to like it

... but the usability (at least on macOS) is not good. It doesn't automatically update to show if your pattern matches. You have to click on "Options" or somewhere else in the UI to make it update. Sometimes it simply doesn't update or show your pattern at all, even though it is correct.

This makes it not at all useful in trying to find the regex you need. It's rather frustrating.

First impression, I agree with the other guy, needs work.

But it works and works pretty decent. Major buy though: pressing ‘return’ crashes the app when typing in the ‘evaluation text’ area. I lost my regex like that :( Pasting a value in with new lines works fine though.

Another bug is that if your regex is line enough to wrap to the next line, when you delete someone at the start of it, making it short enough to unwrap back into a single line, the cursor moves to the end of the regex and you start removing characters from the end instead of where your cursor was initially
