Concerns about migration of CEP extension to UXP

[pklaschka]

@JohnMore

No support for persistent panels. Currently there is only support for Modal Dialogs, which are expect to be invoked and then closed. Our CEP extension relies upon a persistent control, which the user logs into once.

At least that just got “resolved” with today’s update – see Building a panel · Adobe XD Plugin Reference

In ability to access the user file system, in particular the Download directory. This will break a few features in our application which rely on being able to read information from this directory.

So basically, you’re asking for support for “peristent file system access”? In this case, take a look at Persist file references

@JohnMore

Most critical UXP is “not a browser” and as such will only support a subset of HTML. Our extension relies on being able to run another web application within the browser control supplied by CEP, in an iframe window. While there is currently no list of supported HTML, it seems likely that iframe will not be a supported HTML element.

May I ask what you’d need an iframe for? If I may be honest, I can’t think of a good reason to use it (too big are privacy concerns associated with it). Could you possibly elaborate on use-cases here?

By the way: welcome to the forum
