The tag line for your product is “looks like a spreadsheet, acts like a database”. That being the case, please consider that many people/companies will in fact want to replace most of their spreadsheet use with it! Which in turn expands your marketplace exponentially.
BUT, in order to do that, you need to give us a folder hierarchy with simple detail views to manage the hundreds or thousands of bases we will have. Right now the huge icons in list view are IMHO rather silly if you want companies of any size (who will quickly have hundreds or thousands of bases) to be using this.
Thanks for considering.
