Add clear all data option

Is there a way to delete all the files and macros without having to delete one by one?

Your os command line can be used instead of a GUI click and delete.

These remove the entire directory/folder -
shell: rm -r uivison/macros/;
windows cmd: rm uivision/macros/
; rmdir uivision/macros/*;

I don’t want to delete it from the whole computer just the particular browser

Perhaps this would be a helpful first step? How-to: View Local Storage in Chrome and Firefox

Place your Macros in a folder. You can delete then the folder with all it’s macros inside. That’s how I do it.

Yea that’s slow and tedious
