@bardi 's Tusks app is nice, but it's still early days.
I tried making my thread in FediThready because i prefer the way it chooses to chunk up long posts - and lets me control that if i want to - as well as how it lets me review the full thread.
However, FediThready can't post & doing a long thread 1-by-1 with the Mastodon UI is... "sub-optimal"
SO I used FediThready to make & review the thread & Tusks to post it. It worked quite well.
