Hello,
It's just me here, single developer so there is a lot of work. Sadly the last few months I've been working on mostly "refactoring" which doesn't add new features but it needs to be done (Chrome is forcing all addons to use the new "Manifest V3" by the end of January!).

But that's over now so upcoming releases should finally add some new features I've been promising months ago.

And regarding the Pro version, it's what paying me. I'm working on my addons full time so what you see on my Patreon page is my actual salary :(. It's not exactly a good business to make addons for free.

But you are right that I'm keeping my change log way too technical. Still, I think it's better than just write "Fixed bugs" like many other addons does.

Best Regards,
Juraj Mäsiar
