I will never understand the need for a shit load of tabs for personal use. Work/school stuff, sure, but having tabs open for stuff "in case I need it later" is insane. Bookmark it.
I have vertical tabs, so I can see ~30 tabs clearly on one window. Long time non-visited tabs also use no resources. Bookmarking would just be one more click, moving the tab somewhere not easily visible.
My bookmarks are clearly visible and take only a single click to open. If you didn't have a ton of tabs just sitting there, maybe opening a new one wouldn't "move it somewhere not easily visible."
My bookmarks are on the same level as my address bar, I lose no space to this other than having a slightly shorter address bar, which is too long anyway.
If you go to a library and study, you have some desk space in front of you, would you spread out your stuff (e.g. notes, textbook, laptop, supplementary books) to try and get it all out?
Likewise, does your work desk (say at home) have a bunch of stuff on it that you don't use moment-to-moment, but you keep them in close proximity because in the event that you do need them, the effort (or energy) expenditure of having it contribute to clutter is less than the amount it would take to get it or find it in the event you needed it?
Sure, but I don't consider the less than a second of waiting for the page to load to be an inconvenience. Maybe you're saving milliseconds by having your bukkake of tabs, but I don't need to reference things that quickly.
