allow resizing to be more drastically narrow
It seems plugdata forces a minimum box width for objects, and when you're resizing them it prevents you from going "too narrow".
But Vanilla allows them to be as narrow as you want, even just one character. I know that for some cases it would be silly as it even forces the object to increase in vertical size, see [bang] below.
I think it is a safe bet that no one in their right mind think that is a good idea... judge me if you will, but I'm making a moral judgement.
Well, anyway, sometimes I do almost abuse this feature to save some space and I see now that opening the same document in plugdata will ruin things a bit because it won't respect the box width that was saved in Vanilla, and won't let you narrow things if you will.
Here's [b] saved in vanilla with a 1 character width and opened in plugdata
and now [adsr~] saved in vanilla and opened in plugdata
In both cases, in PlugData, trying to narrow the box width freezes at that minimum point
