Hi Adam, it is advisable to read the instructions first, before posting false reviews ;)
I addition you have the possibility to contact the developer in case there is something you didn't understand.
Have a good day.
You are just posting false statements and insults and call it "being honest".
And you don't even have to create a GitHub account, but can simply write an e-mail if you found a bug or don't understand how the extension works.
And clearly you don't understand it, because you haven't even read the instructions.
If with "bookmarks" you mean Textmarker's history: Textmarker doesn't store anything you didn't do on your own. If you say otherwise, then you clearly lie. Textmarker will save your highlights to the history, and when you don't like them being saved automatically then just disable this feature - where is the problem? And the content of the history is "garbabe"? Well, it's what you saved, so don't blame anyone else but yourself. Ridiculous messages? You can disable any sort of notifications - they are meant to help the user, and clearly you need help.
