Photoshop started as a Mac app, so that alt key usage is maybe legacy keybinding convention. 🤔

The Filter menu is classic destructive editing (as you found out). Adjustment layers and effects were added as a non-destructive feature. It’s annoying that not all of the filters are available non-destructively. 🙃

Thanls for sharing how this app performs. i was curious (but not curious enough to install it). I’m glad you had all your fonts available. 😅
