> it taking quite a lot of CPU Yes that is fixed. The reason for slow performance + high cpu usage on electron/webkit apps was just the sheer amount of mach ipc calls (from the many many <div> layers) needed to be made to fetch the entire UI element tree. This has been fixed two days ago Heres the solution for those interested: https://github.com/dexterleng/vimac/pull/190 I was also using a bunch of async queues instead of just a single NSThread which likely contributed to high cpu usage, and that has also been fixed. > warning that I am using a screen reader.

In Show HN: Vimac – Productive macOS keyboard-driven navigation
Hello all! I am a student from Singapore who was introduced to Vimium by a friend two years ago. Vimac is my attempt to implement Vimium on an OS level. I have shared this app on Reddit about a year ago. Since then, the notable changes would be a major performance buff in webkit/electron, force keyboard layout, and reducing the overwhelming no. of hints to what is just "clickable". It is open source at https://github.com/dexterleng/vimac/. Do let me know if you have any questions!
