niloc Okay, so if such a thing happen, how would that update work like? Would it literally overwrite everything or would it update certain front end styling only?
We can't know for sure at this time, a lot of styling will be refactored and improved, and some structures in the process.
The main refactoring that will happen is mainly switching to grid/flexbox and that'll be quiet a number of sections.
niloc What would your advice be to manage this potential problem?
It will entirely depend on what you customize and how much you customize it, as well as what changes actually took place, so it's really not easy to say, best case scenario you will have to update a few lines of code to have your custom styling work as before, worst case scenario you might have to rewrite your code, it also depends how you write you code.
Also remember that this is most likely gonna be in the next major version, and we've only just released 1.0
