I work in extremely low density (8 px/m) would it be possible to add a feature to save your own custom Pixel Density Presets to the drop down list?

Another nice feature would be to add the ability to paste from clipboard from other programs such as Aseprite. Say I have an image open in Aseprite and I select an area and copy it, being able to use the paste tool in Pixel Art Studio to add it to the texture.

Thanks for the suggestions. Both are already being developed and planned for the next major version v1.2.0. You can follow here: https://github.com/orgs/PardallTools/projects/1/views/2
