seems like figma got so excited about the fact that they could, that they forgot to ask if they should.
this should be a user configurable setting.
i would think this should be off by default as has been said. at no time have i benefited from this feature and now it is actively impeding my work. granted i can work-around it by creating two distinct text boxes that appear as one, but i should not have to.
i also think this setting should be file specific, as it seems very likely that in one file a designer might want this (not me personally, but there must be people that like it), but in another file this might be unwanted behavior.
until the automatic lists can be styled to suit the project, i do not ever see this feature being of any value. figma is not a word-processor and the automatic list feature in ms word is problematic. i have seen myself and others fight with it so often to get it to do what we want it to, that it takes more time than just manually indenting and numbering or bulleting. and microsoft has been working on that for decades. that is why i use indesign or sublime text for any word-processing i need to do.
the auto list feature was an ill-conceived, poorly implemented waste of effort. should have spent the time on branching, auto-layout fragility, nested component controls, or any other of the so many feature requests on this forum.
