I’ve always found it annoying that the name of a modifier is hidden unless you set an unreasonable width to the properties panel, justified only to show the modifier name, but creating useless empty space for all other elements of the properties panel, and reducing space for the 3D view.
Although the idea of having modifiers with only one line on the header sounds better, maybe adding one line so the name of the modifier could be visible would be a good idea, or some other solution. I would keep the name, up/down arrows, and X in the same line and put elsewhere the display options.
EDIT: After posting this I saw there’s a thread about papercuts. I should have posted there. I can’t delete the post. Could any moderator delete this to make my contribution less notorious?
