Yea, the workflow is a bit different. Not having a concept of fill opacity as separate from layer opacity forced me to change the way I do certain things, and having certain retouching tools grouped with the brushes was confusing at first.

For years, I didn't use anything besides Adobe CC, because it's "industry standard," so I've never given anything like Affinity a go in earnest.

With all FLOSS design tools, I had to have a bit of a reckoning with myself; like most people, at first I thought they were unintuitive, until I was able to have a bit of objectivity and found that most of the issues I had with them didn't arise because they were unintuitive; it was just because they didn't work like Adobe tools, which are themselves complex tools that you really can't just pick up on your own without some degree of instruction.
