is there a way to save website bookmarks in stash?
All of the various stash categories, like Studios and Performers, have a place to add URLs. So you can create a Studio and add the URL for wherever. If you wanted to separate your URL only Studios from the others you can tag those Studios as ‘Bookmarks’ and then filter that way.
Not sure of your use-case but I hope that helps.
I was thinking more along the lines of a favorites tab for websites. For instance you find a video on faphouse that you want to download at a later time. Or a place to centralize all of your favorites tabs from multiple websites.
Kinda like having its own tab like scenes but the source of the video is a link to a site.
You can create fileless scenes by clicking New at the top of the menu bar on Scenes page and then add the link. You can also use community scrapers or metadata manually to them.
