I know, I can then click save and add it to the page. But it's annoying having to open the editor, click upload, upload it and wait, then close it, open the gallery, search for the file, click it, click save and exit the editor. Especially since files take a couple minutes to show up in the gallery search.
Considering before I could just click two buttons and upload images straight to the gallery, it's rather annoying that they've changed it.
Also speaking of galleries, what happened to the pop up that allowed me to change gallery shape, width, text colour, position etc. Do I need to learn coding just to do something that was easy to do before?
If I recall correctly, those were also accessed using the same "add image" button, correct? If so, then yes, you now have to use source mode to change those same things. The pop-up editor which allowed you to change those things were all part of Fandom's custom gallery extension which they are working towards retiring in favor the the software's default gallery system.
