Thank you for your detailed review!
I can agree with it –we currently have a number of small issues that need fixing, part of them emerged due to the huge workload we've faced. We're working our way through them day by day, without days off now. In a couple of weeks, all the points outlined would be solved, just as you normally debug and polish any complex digital product, and then the updates & upgrades would come.

Speaking of the note titles - we've already fixed them, we expected users to add a header that we'd use as a title, but people don't do that, so we automated title creation.

The highlights and YouTube fixes are coming next week along with the collections formation logic.
The CSV upload should have more guidelines from our side as CSV can vary a lot, and we need to map them to our database – working on that too.

We're serious about building the best digital library with a co-pilot for professionals & teams and have just secured way more resources than we had before to run 3x faster and build a better product.
