Wow! Lots of food for thought. These are all valid considerations for me to mull over. I had perhaps 100 notes in Catch so far with only two streams and had not yet had a problem finding anything but it just seemed too limiting knowing that I could only create one more stream for free. But one concern I have with a too tag heavy approach is not wanting to have to spend 5 minutes on every note looking through a huge list of tags trying to decide how many are truly applicable and important to a single notebook approach. Perhaps I am overthinking it tough or getting the wrong idea about this approach? I'm not praising Catch or criticizing Evernote but simply trying to complete my transition - but there was one feature in Catch I really liked that I have not yet figured out how to do in Evernote - or if I even can. That was an easy way to narrow results with multiple tags. For an exaggerated but realistic example, let's say I had 500 notes in a "Hiking" notebook. 250 have a "trails" tag and 25 of those have a "New Hampshire" tag. Other trail notes may have tags of "Virginia", "Tennessee", etc. for trails in those states. 20 of the 25 trail notes tagged "New Hampshire" are tagged "peaks" and 10 of those 25 are tagged "waterfalls" Many of the VA and TN trails notes have varying mixtures of these two tags as well. Now, let's say there are several other notes in this notebook also tagged "New Hampshire" but not "trails". In Catch, while on either All Notes or the Hiking stream, if I pulled up the tag interface and selected trails, it would show all 250 notes tagged "trails" but no other notes. The interface would also show that these notes included 25 New Hampshire tags, X number of Virginia and Tennessee tags, as well as X number of waterfall and peaks tags. The notes with New Hampshire tags but NOT with trails tags have already been excluded. If I then select New Hampshire in the list of tags it will then display only the 25 notes tagged with both "trails" and "New Hampshire". It will also show that there are now 20 notes tagged "peaks" and 10 tagged "waterfalls". Continuing, I select "waterfalls" and am left with only the 10 notes tagged "trails", "New Hampshire" and "waterfalls". I will no longer see notes tagged "waterfall" AND "Virginia" for example. Nor will I see other "New Hampshire" tags that got culled when I originally selected trails. Is there anything similar and equally easy in Evernote? If not, that would seem to justify a larger number of notebooks to my way of thinking. Rick
