You underestimate the sheer volume in my hippocampus dedicated to tracking tabs.
… Kidding, mostly. Because generally tabs are grouped together in a way that makes sense so it’s easy to remember. These 10 tabs are me researching a new tool… A couple tags for articles I will surely get to… Then these 15 tabs are documentation for XYZ… Those 5 tabs are YouTube videos I want to watch… These are three Wikipedia searches that popped in my head and oh look a couple songs I want to listen to before adding them to my playlist.
If I want to find a tab and they are fully minimized then I click on the group with the relevant icon then I Ctrl+Tab through them until I find what I want. Perfectly reasonable.
I swear it makes sense and bookmarks are not an adequate replacement.
