Sorting folders or accounts seems like an advanced feature where most
users are happy with the alphabetic sorting (like most file managers do
too). Adding such a feature needs a lot of UI for a questionable
benefit. So it would be best if an addon did it first so we could then
evaluate it. See https://bugzilla.mozilla.org/show_bug.cgi?id=1359410
where I offered support for allowing an addon to manage the order of the
accounts. It seems to have stalled there, patch for TB is ready, but the
(already existing) addon update didn't come. So in this case please do
not blame the TB core developers.

I assume the price for this is the increased RAM usage :) We inherit all
the rendering layers from Firefox. Also I realy doubt the removal of XBL
and XUL elements and replacing them with pure JS duplicates (Custom
Elements) has any positive impact on RAM usage. I'd guess it is more
wasteful.
We haven't added many features in TB that would answer the doubling of
the RAM usage. But sadly we don't have tests that would catch any such
increase.
