Some big challenges are emerging as Webflow grows and systems scale.
A navigable cross referenced detail quickly becomes essential for any site that features complex or numerous simple interactions.
A few problems due to the lack of a detail view or visual prompt:
It is easy to accidentally apply an interaction to an unintended background element and the results are pretty dramatic. Try init hide - accidentally applied to your body and your site.
Changing the name of any class element that has an interaction applied is a disaster. The new name won't break the existing interaction, but those instances are never targetable by any new IX using the new name. To do so, you have to accurately restore the original name (from memory) or start over and rebuild the IX after removing any existing ones (ouch). I would like to somehow obviously know that the IX is affecting that class...
Some type of cross reference visual tagging to identify element and interaction use is an important portion of the the solution I think. Currently they are hidden deep in IX and completely invisible absolutely everywhere else. Especially targeted elements that have no direct application that would show lit up in the IX list as an effector / driver.
Currently you cannot browse the navigator and see when any of the directly applied interactions that would light up in the lIX list, because both tabs (navigator and IX) cannot be open at the same time. Even if they were both visible, it would not pose a solution for targeted instances.
Some type of micro tag like the one that appears top left when any element is selected would be a great help for finding and selecting an object that had an interaction applied, but targeting other elements or heavily nested elements makes that a challenge in the nested hierarchy of the designer. I think even a tiny key (colored dot) applied to the element in the navigator tree and on an object in the layout would be a huge step to identify that an interaction is applied or affects that object / class but it would need to include ones that are indirectly targeted.
A filterable by type / search based solution will eventually be a necessity I think as Webflow grows and practical site complexity explodes along with new systems and capabilities. The 3d apps I use rely on them heavily to make enormous systems and interactions and associations across numerous lists thousands of times more complex instantly scale to be become understandable.
If you would like examples let me know and I will try to put some screencasts or screenshots together for discussion.
