is there a rough ETA on this, this summer vs next year? Need to switch from YNAB after 10+ years as I now need native multi currency support

This makes no sense to me as the most upvoted feature for you guys to work on. This is a tool that you should use once a month and look at a good large screen when you do.

Mint would be a great model. Just not as slow or bloated. It's been slow for years for no good reason. Should be lightning fast, it's just a little bit of data being updated/exchanged over the wire or synced to a local database and then that is synced over the wire. Depending on your approach. Simplifi's app isn't terrible but I liked the original Mint native app interface that you could just edit in-place instead of an additional modal for everything :)
