I have used iOrganize extensively for a long time and I would not want to be without it. The introduction of sub-categories in Version 6 has made it even more useful. Allowing you to group similar logs into a single document should make searching for keywords much more effective. However, the search function does not work very well. "Search" only locates keywords that are in Notes within the Category being searched. It does not find keywords that appear in the names of Sub-Categories, or that appear in Notes within Sub-Categories. Really useless. I hope that this will be fixed in a subsequent version. Two other things that would really help...
Being able to rearrange Notes or Categories in random order by dragging and dropping.
Being be able to promote or demote categories as in Mac OS Mail.
