I've spent the last 8 weeks or so building the spreadsheet tool I want to see in the world. CSVs as first-class citizens with the ergonomics and speed of my text editor. It's been a great opportunity to explore building GUIs in rust, and to really experiment with coding assistants.
I'm looking for alpha/beta users https://cassava.dev/.
Why use Cassava over other options, such as Excel, CSVLint, or Notepad++?
Also, have you considered supporting Windows and Linux?
I like working in native apps on my Mac for spreadsheets, so I've used Numbers a little bit, but if you have the same iCloud file open on two machines they conflict and don't merge nicely. Does this have a better story there?
