i wish all your tools had some kind of preset save system where we can share presets or name different user cases. I love your tools alot! Keep up these small gems! Good luck with sales also on steam.
You can right click any slider to input the exact value that you want, exceding min/max values too. Projects are essentially what you say, the only difference between a project and a preset would be that the project includes an image, which can be changed at any point.
