I want an app that acts just like sheets of paper, or a sketch book.
I simply want to practise drawing (colors and painting optional) with the drawing tablet I got.
I want to be able to start up this app and doodle on a whim, so apps with really long startup times, tricky workflows etc. won't be very convenient for me.
So, I am hoping to avoid Photoshop and co. etc. because they are so heavy, and also I'd have to set up canvases etc. every single time I want to sketch something new, save and load files on my own, thus know how I've organised my disk and manage this organisation myself.
I hope there are lighter-weight apps that I can just ... draw/doodle in, and then archive old drawings somehow.
