Please forgive my ignorance on this subject

The correct link for the new beta version of Krita, can be found at

        https://krita.org/en/item/first-beta-out-for-krita-4-4/

I downloaded the appimage a few minutes ago, and put it in a new directory called "AppImages."

In addition, there is a plug-in that you can also run, but that
is all above my paygrade.  ( See G'Mic for Krita ).

In the link below, is a screenshot of krita 4.4. beta working nominally in Gnome
3.38 ( using my Rawhide install with custom wallpaper )

Disclaimer:    I had no earthly idea what the "chmod" command did until about an hour ago.
I have been using Linux a little over three years for simple household task and my hobby-business.

I did try to run this from terminal and got wayland / gnome area messages and that a python file was
missing, but I did not get that when I double-clicked on it in in Gnome Files

At the present moment, I only have doodling experience with GIMP and Krita as shown in the screenshot.   
But I once did a couple of real drawings back in 1993
( Microsoft had a drawing tool in Word 6.0 in 1993, if that rings a bell with anybody ),
and I was proficient with AutoCAD 12 back in the mid 1990's.

So here is my next question:

Do some appimages contain proprietary blobs.    If so, that would ruffle some feathers, if Fedora
users recommended those appimages.    Is that right ?    Or does that sort of fall into the same category as
installing third-party repos ??
