[Affinity not an "identified developer"?]

When I right-click on a .JPG image file, Affinity apps are no longer showing up as options in the "Open With" context menu under Mac OS Catalina (attachment 1).  Even when I select "Open With>Other", select Affinity Photo, and check the "Always Open With" box (attachment 2), I get a dialog warning me that "macOS cannot verify the developer"... (attachment 3)

HOWEVER, when right-clicking on .PNG, .GIF files, the Affinity apps appear in the context menu as they always have!

Note: I *have* opened System Preferences>Security & Privacy>Photos to allow Affinity Photo to have access to my photos, but Affinity Publisher is the only app that appears in the list (attachment 4).

I *am* able to open Affinity Photo, drag-and-drop the .JPG image into the editing window, work on it, and save it back out; I just can't open the image with a right-click.  Would really like to have this functionality back.  Is this an Affinity issue, or an Apple issue?

Thanks!

[Universal Design Color Swatches Palette Built-in?]

I'd love to see an update (for all apps, but particularly for Publisher), with a Universal Design color swatch "built-in", so that I can be sure I'm using color schemes that are accessible to those who are Deuteranopic, Tritanopic, Protanopic, etc.

(Sorry if this exists here somewhere already — I find the forum exceedingly difficult to search/navigate).

[Text sizing]

Sorry if this is already here somewhere, but I find this forum exceedingly hard to search for topics.  Also, if this function/feature is already present and I just haven't found it, I would love guidance.

That said, I'd dearly love to be able to relatively resize selected text by one point size up or down with ^A and ˇA buttons.  I know I can size the whole text area by dragging a corner, but sometimes I don't want to size the whole text area, just the text inside it, and as far as I can tell, the only option is to set a new absolute text size for the text box and then go through reformatting if I have several text sizes within the same paragraph.

[Measuring and Line Length]

Just wanting to add my voice to those requesting a measurement feature for lines/curves.

At the moment, I am using a workaround of rotating my design to zero rotation, drawing a horizontal line from point-to-point, looking at the Width measure reported in the Transform window, then deleting the superfluous line and rotating the design back to it's original orientation.

[Footnotes/Endnotes]

Let me add my voice requesting footnotes/endnotes, and conversion between them!
