Made my first Image Filter Protocol and went through similar stuff.
- The "Edit Port Value" popup from the published input bar crops at the edge of the screen (but that’s true for all ports on the canvas).
I think the popup should align on screen ends somehow, don’t remember how that was in QC).
- No scrolling of a cable on the canvas when the Published Ports Bar is visible.
I understand this happens because we have to reach the Published Ports area. Scrolling could perhaps be supported either or both when we reach the composition window's end (or even half the Published Ports Bar area), when we reach the published port area for more then a second without connecting the cable, or drag to an area of the Published Bar where no ports are published (empty bar).
Because right now we have to hide the Published Ports Bar to allow dragging, which is done quite quickly thanks to the close button on the bar itself, but when you want to show it again, you have to go in the menus etc. Perhaps a show/hide publish ports button on the editor would be faster, or a keyboard shortcut to show/hide. This would however be less important if scrolling was enabled. A kind of a workaround, as @Azyrock pointed out, is to use some combine scene nodes. Or share the published inputs and output ports with some « share value » nodes That way you can hide the Published Ports Bar and use the shared values instead.
As Philip pointed out, impossible to reuse an already connected cable from published ports. You will have to drag a new one.
No replace cable possibility on the published output ports. You have to remove the cable first and reconnect a new one.
As Philip mentions too, quite hard to drag a cable from the published inputs. From the port value it doesn’t work, from the port itself it resizes the width of the published ports bars, so you have to grab the cable beside the port, on the blank canvas itself, but not too far from it. I guess cables should be draggable from both their names and ports. The top space of the Published Bar where "Inputs" is written would be enough as an area to resize the bar in my opinion.
