Of all the weird usability quirks Sketch has held onto over the past few years, the automatic propagation of changes from one instance of an applied text or object style to all other instances was probably the most maddening. So it's great to see that finally resolved in 3.7 with manual style sync.
Next on my Sketch usability wish list: the ability to set the fill or stroke on a group instead of having to go in and manually select each of its objects.
Yes, this issue alone was a complete blocker in my opinion, thank goodness it's been resolved. 100+ page documents could be destroyed in one simple action of pasting a styled text into a box with a pre-existing style assigned. (It was irreversible via an undo).
