preserve style "overrides" when syncing

[chrischernoff]

Say I have a black 12pt bold text style "foo" in my library, and a layer "bar" in my working file is using that style. I like the other attributes of foo but on my bar layer in my working file, I change the color to blue to be a CTA.

Unfortunately, when I sync my library styles, bar's appearance is once again set to black to match foo's state in the library.

Is there a way to initiate a library styles sync without overwriting any layer styles that deviate from the shared style?

ah tricky - not easily, because Sketch doesn't currently distinguish these as "overrides" as well as it does with symbols.

It's definitely possible to write a comparison algorithm, diffing the library state, the document state and the overridden layer state, but it's fairly involved, and not something I can personally do short term
