Wish for funktionality: write inactive tabs to hdd or make them sleep

There was a proposal to do something along these lines a long time ago,
but nobody got around to implement it.

However, note that the underlying OS will often be able to write a group
of tabs to disk and unload them from physical memory if they are
inactive. The OS will still report a considerable memory usage, but that
memory will actually be disk space.
