This behavior is still in beta 1.6.0.85. Do you have any news?
I can envision uses for offset pasting but as a rule it makes a mess for my workflow but an OPTION to invoke (or suppress) that behavior would work
Also as to not insinuating it is a photoshop replacement. All your advertising and some of the tutorials suggest just that - the Affinity family is a less expensive alternatives to Photoshop and Illustrator. The more you deviate from the workflow of those programs the less of a contender you will be. You may find yourselves basically back to Photoplus (a great program for sure, but not a contender for the Adobe market)
Thanks
