Justus, Just wanted to say thank you for introducing me to Marimo! It's been the missing piece in accelerating my beancount usage, Fava has always been way too slow for me.
I submitted a couple PRs to your marimobean, one is a tiny bugfix on the pnl if the selected date range doesn't include any amounts, and the second is a faster net worth calculation that makes it practical to calculate daily net worth (with commodity price conversion to a target currency) on large files. This is a speed up over Ev2geny's version. I might also suggest that for most practical situations, it's not necessary to visualize net worth per-day over large timespans and you can get an additional speedup by plotting once/week or /month or /year.
