Likewise (well, I don’t know about “hundreds,” haha, but dozens, certainly). Ever since tab-searching became a thing (% in the omnibar of Firefox or Ctrl+Shift+A in Chromium), tab count or location in the tab strip doesn’t matter; just jump to whatever you need. This has been tremendously game-changing at my work which also calls for dozens of spreadsheets to be accessible at a moment’s notice based on the task at hand.
