so there's many way to create an exportable layer in Sketch, like if you make a layer exportable in a symbols and you use that symbol constantly in your project (ie social icon in the footer) you will then have that assets repeated over and over in the assets panel of inVision (and of course into the assets folder) for each artboard that has that symbols in it, and that's not very smart.
So, my question: what's the best way to manage different type of assets made in Sketch based on the different layer "case" to not have them repeated over and over?
If into a symbols I have a rectangle with an image fill, which I make exportable, and to that rectangle for each instance I've replaced the filled image with others, how Craft and the assets panel behave or how should I do to have in the assets panel all the image I need and not a weird random selection of the one I've upload? That already happened to me.
And on top of that, is it InVision Sync still needed? If so, is it better to manage the assets from the finder's folder or via web?
How InVision read and manage the nesting naming hierarchy of the assets (filename > page > artboard > layer) or how should we rename files in Sketch for a better export and read in Craft/InVision?
Many questions for such an important matter which after 2 years I still haven't managed because I haven't figure out how the software behave and support I've found it's pretty lame...
