Same. I’ve compiled a custom variant of Iosevka for terminal and code, because I want to have some chars in a certain way, especially the 0 and the & for even better readability. I used to have Monoid for code and terminal, but it the pixel perfect size for 12pt was getting too small for me and my eyes are not getting any better. Iosevka looks better even after some hinting by the OS.
On the rest of the desktop UI I use B612, because it is very ledgible, I recently switch over from the hyperledible Atkinson font. Before that I had Gidole on the desktop. Very pleasing, but not that readable at same font size.
I manually add receipts from my partner and myself to a CSV file, too. I have a custom R scripts to calculate the monthly contribution. This way we can see who paid more/less each month and needs to componsate.
In the future I want to plot graphs to see how we are affected by inflation over the past years.
