I also! Today I started to examine Evernote and it was simply great! Until I find out, that only one level of notebooks can be made :(. To use Tags to achieve hierarchy is just strange and I can't understand why the notebooks are not organized in hierarchical levels via the Stacks? This would be much more intuitive and reliable then the Tags. Tags can be just Tags, but the Notebooks needs to be organized hierarchically. Now I am thinking to uninstall Evernote agein :(.
