I have workarounds for pretty much everything at this point, but if I could have ONE thing, it would be the ability to have shapes and DPs dynamically resize themselves to the height or width of the text they contain. This would clear up a good 40-50% of the headaches I have.
If I could have a second thing, it would be the ability to explicitly set all the mobile / device stuff we used to be able to set in previous versions of Axure. Back in those days, you could effectively build an actual responsive-ish webpage with no dependencies on the prototype player. Linking directly to HTML files is super useful in a lot of cases.
A way to apply custom CSS that isn’t the “open link” javascript hack would be grand.
Auto layouts and constraints a la Figma would be a neat thing, too.
And we’re getting so close with cloud inspect, but there are still a lot of bugs. Positioning of stuff is often off, it’s hard to inspect things that happen on mouseover, lots of things show up as images rather than CSS attributes. We still don’t have an easy way to embed fonts, and inspect sometimes says weird things when we do embed using the base64 font-face method.
Edit: Inspect should also include animation specs. Alternatively, give us back the console on published prototypes. Or, why not both?
