Allowing for styles to encompass all of the data in any given section of the properties panel and be able to combine them into a meta-style or object style.
Another way to think of it, if you want to save a stroke style you could save all of the information in the stroke section of the properties panel and the stroke settings within that style. Weight, color, style (dotted vs solid), sides of object (if applicable), etc.
Expanding on that, being able to save the style from each section of the panel to a meta-style or object style (akin to adobe illustrator or indesign) so we can use all of the same styles on a new, unique object without using components. Sometimes two objects need to be styled the same way without them all being tied to the structure/content of a main component. It would speed up the use of components and variants a lot as well.
A good example is making a different meta-style for each of the states of a button. You set the fill color, stroke color, stroke weight, stroke joins, effects, text, etc. Then you save them all as one big meta-style. Further down the page you want to make a set of clickable cards. Not appropriate to use the button component but it’s different states share most, if not all of the same settings. You could make the card, one click and all of its styles for the normal state are applied. Make it a component and add a variant. One click, change the whole card to the hover state style and move on to the next variant in moments. This way all of the states of the cards and the button will look the same with hardly any effort, even though they can’t be instances of the button component.
