I tried out Krita’s 4.3.0 beta and all I can say is that I’m pretty impressed. First of, the snapshot docker has tons of potential. I imagine seeing myself using it by creating “checkpoints” whenever I’ve reach a major milestone in my illustration and then “re-spawn” to one of those checkpoints whenever I want to restart without restarting entirely. Second, I think the magnetic selection tool is cool. I could even readjust the points to some extent. And the beta watercolor brushes…I love them. I particularly like the grainy water color brush. I don’t know why but I think one of the reasons is because I enjoy the texture it makes. It’s almost like the real watercolors I used at home.
I couldn’t go as much deep as I wanted to on trying the beta because apparently it didn’t sync with the shortcut keys I placed on my pen tablet for Krita. I guess it’s because I used the portable zip folder and I’m so used to using my shortcut keys 
.
Overall, the beta is hyping me up for the official release as Krita seems to be getting better and better.
The art looks organic with these.
