Easy User CSS extension
The name is Easy User CSS and I think it tells a lot about it's functionality. Before this extension you had to create new file for every site where you wanted to have user css. Thanks to my extension you can just click on a button, write the css rules and press "save" - that's all! You can also use "Live preview" that shows the effect of styling immediately during writing the CSS rules.
You can also use this extension like a web developer to quickly see CSS changes.
So! Download it now and tell me how you like it!
BTW I don't plan to create second Dragonfly so if you have any wishes then make them simple^^
