Hello, I'd like to request a feature if anyone would be willing to help with this. Based on this issue in particular,
Add filtering options for The Main/ComboViewer using the code of the FX swatch viewer · Issue #4642 · opentoonz/opentoonz, I think it'd be really useful to have some kind of drop-down somewhere that allowed you to change the filtering mode for zooming in and out in the viewer. Basically every other artistic program I know of uses bilinear filtering for zooming, as this lets you see the texture or cleanliness of your lines at zoom percents other than just 100, however Opentoonz doesn't for some reason.
