Hi, thank you for bringing this useful tool, which I definitely recommend. - The Dark theme colors are well chosen. However there is still much room for improvement regarding the interface, which is not yet very practical and still feels a bit messy/poor. I never remember how to find the output text, in the "replacement mode", simply hidden under my keyboard. I feel lost even though it is such a simple app, lol. The top-right menu could use icons. Pay in mind it's just constructive criticism :)

I didn't realize how good this app was until I really looked into it. Now, I feel like I can write any kind of challenging regex expression. I believe every science enthusiasts should know regex, that will make searching and finding any written specific text a pleasure. You can even use regex searching things in google.

I do not know why the people who are given this app such a high rating. First off, you cannot open files. Secondly, the text window is way too small. Thirdly, multiline is backwards. ".*the" shouldn't select the entire text when multiline is disabled. When disabled, it should stop at the first "the" it finds. Fourth, there is no find next. ..and lastly, but not the lease, there is no text field for you to enter a replacement string.i
