So at first the button where I could adjust all my tools disappeared. I could only choose the colour of the brush/pen/etc. and that was it. I managed to find a setting that allowed me to adjust brush sice and the texture, but it's super difficult to find it each time and I'm still missing the settings for adjusting the stabilizer, brush density, etc. ... how can I get that back? Setting everything back to how it was before doesn't work. Also, while trying to get my settings back, I suddenly lost all my other tools (pen, paint, airbrush, ink, EVERYTHING) as well! Now I can't do anything at all. Can somebody help me to get my settings back to how they were in the beginning?
