Great stuff!

Could you add support for shorts as well?

Works fantastic

It marks clearly watched videos. It's easy to export and import watched videos from a browser to another.

I can't even remember what Youtube is like without this addon. Incredible work.

Very useful, nicely structured, would be 5 stars if
1) it didn't slow YT videos to an almost complete lag; (database 4495)
---Would marking the text (purple or red) instead of the image use less resources?
---I have many unloaded tabs of videos, is something collating all those unloaded tabs each time?
2) it said when each option marks a video- do any mark when they are queued? When do the YT options mark them? When does history matk them
3) once you have a collection in memory, which ones are needed to update it?

Great app. Easy and smooth to use.

Suggestion : Would love an option to change the date stamp format to dd / mm / yyyy. The default one is kind of backwards...

:)

Very useful tool !
Thank you

Works great in standard desktop mode, does not work when viewing youtube from the mobile feed, on a computer and a regular browser....

Works even on different computers. You only have to log in to your gmail and you see all the marks videos you´ve watched on another computer

extremely useful and works perfectly. the only thing i miss is an easy way to regulate how much the thumbnails of watched videos get dimmed. otherwise an A+ extension that i hope lives forever.

Please add an option to have the extension hide the mark the videos as not interested or hide them in some way please.
