Dynamic sections based on "search"

as currently Cintanote didn't have the following functions:

1) saved search: which is easier to locate the search we regular check, this is more effective than search history, and more details than find stuff by tags only.

2) shows the tags based on selected notes. which is the tag > note reversion, which some case is quite useful, as: find what's most tagged notes in current month...

but I think one thing can rule this all, that's what I called "Dynamic Section", this based searching, and save the searching as section.

what do you think? hope that's not very hard to Implemented in Cintanote.

Thanks.
