Actualy, it is not function as I expect... (selection antialiasing) ...
I had PS3 before i buy Affinity Photo, and I must say, is possible use it AP, but still it is not same quality as PS for everydaywork.
Standard functions which you use EVERY DAY like are magic wand or laso are more complicated and it is nightmare to use them ...(OMG laso is like bad joke = why is not here trace-line some thin dotted line but huge blue line where is not possible to see what is behind???..and you want continue by selecting out of corner but picture is not moving automaticly if you stay by laso in the corner??? WHAT???) .....
OK, maybe background removal function or clone function or something like this is better then in PS (im my opinion), BUT thouse functions 90% of users not use every day, but selection, laso, magicwand, or else they do!
Please, do it more user friendly ..:(
