It's mostly just dumb little things. You can transform elements using exact numerical values in some contexts, but sometimes you just get a drag handle and can't be precise. You can put tables in a document as standalone frames, but you can't include them within your text story so they reflow properly. This is basic stuff for graphics and DTP software respectively, yet Affinity can't do them.

But then again, for a very long time very basic search and replace options were missing in InDesign, so as I said before, it's not as if Adobe's software hasn't had its share of bizarre limitations over the years as well.
