My memories of DataSheetGrid components in general is that they are the holy grail of UX/UIs but they are really complex to have all details included. I hope you all the success (and funding). I saw the story repeating itself beyond the base plaform used: Web or Desktop. Having fond memories of stuff like [1].
Agreed, this is the best UI for inputting a lot of repeating data imo. (I am not claiming I invented anything)
Thanks for the kind words, funding is not an easy thing with OSS!
