Hello Appery and anybody concerned,
My idea is to improve a bit custom Javascript and CSS handling. When you select RUN JAVASCRIPT event you can only put your custom JS code in here which is fine and I would leave it that way. However it would be nice to have an extra option to pick the Javascript asset you have already created in your project (from the dropdown for example), so it would get attached to that event. Now I just type manually the name of the function to invoke this JS asset but this solution seems more elegent and useful to me. Of course the exact behaviour is yet to be determined (renaming or deleting JS asset for example) but I am sure there is a good option to solve this.
I would recommend the same approach in case of attaching CSS assets to components.
