  21. I made a drawing app with programmable brushes inspired by tixy: https://fig.sonnet.io It’s pretty fun because the shape dynamics are time, and not pressure/tilt based, so you need to draw in a rhythm.

  23. > but Mozilla is an ad-tech company too now. The recent events related to FF are not that much of a shift, considering that Google pays $20B per annum to its (technically non-ad tech) partners, then 85% of Mozilla's total revenue comes from its partnership with Google . That ship had sailed long time ago. https://untested.sonnet.io/Defaults+Matter%2C+Don't+Assume+C...

  25. I think you can just add it to Control Centre, no need for shortcuts. I made an app for reading in the dark, minimising the amount of light hitting your eyeballs, but I'm still using the red color filter every night. The app is overall darker and more "strict" with how it handles content (esp. images) though: https://untested.sonnet.io/Heart+of+Dorkness and midnight.sonnet.io Overall, reduced the number of photons i…

  29. > it would do a lot more and a lot more sustainably if it focused on the core mission of its browser. Some numbers to put things in perspective: https://untested.sonnet.io/notes/defaults-matter-dont-assume... FF is still a solid choice, privacy-wise (with some manual tweaking), but just in the past few years 80-90% of their revenue came from adtech partnerships, so expect a series of rug pulls like the recent ones.
