I can empathize. I don't really care about the save vs export thing, as I have adapted to that and just go directly to export in the menu.
But, as a long time but infrequent user, I really dislike the changes towards "non-destructive" UX that just seems to spawn endless layers and other forms of pixel buffer limbo that confuse me. Lately, it feels like I'm being slow walked by a passive-aggressive tool that wants to waste my time and mental energy.
I wish there was a "novice" or "casual" user setting option to go back to a much simpler UX, where I am operating immediately on the selected layer. Where a pasted object can be dragged but anchors as soon as I touch something else, etc. Where filters preview but then "apply" immediately. Where undo can revert some recent changes but otherwise the effects accumulate destructively into the current layer.
A naive user may never have to learn about layers, but they are still there when desired. I don't want a layer spawning on their own. I'll make the new layer before I start changing things, and I'll think deliberately how I want that layer filled. Then, I'll resume actions that immediately mutate it.
