1) joplin. a great alternative to onenote.its in markdown and open source!

2) ulauncher (for linux), executor (for windows). oh how i love just typing "az 12345" and it shows my azure devops bug in chrome.

3) obs studio. when i want to force myself to focus i record myself doing the tasks and talking my way through it. give it a try

im away from my computer so this is just some of the things i remember
