I doesn't save the last operation chosen. Every time you have to pick again the operation you use the most.

Great selection of tools. The option to replace the input with the last output is nice. Would be perfect if it filled the input automatically with selected text.

Does exactly what I want it to do! Easy interface.

Very powerful, easy to make quick edits without having to open a text editor. I wish it could do it dynamically (based on what is selected on the page), but that's probably a Firefox limitation. Thank you!
