I just leave the tab open forever
Even with the fancy mobile interface you really just need to store a thumbnail (plus the URL and title) for each tab, and even an older iPhone should have little trouble scrolling through thousands of tiny images.
In Chrome I use a tab suspender extension, in part because there was a bug that bit me alot where it would leak memory of you leave a tab active with a highlight. Don't know if the bug is fixed yet. Tab suspending makes my Surface Pro run better; seems like it shouldn't be needed.
