The main benefit of rtm is smart searches the only problem is i ended up with a lot of them and there is no way to sort them.
To get around this I add the smart add tags to the start of the search to group them together. Here is a screen shot to hopefully explain better.
As you can see if a search is related to time i add ^, if its related to a tag i add a # and related to importance i add a !.
On a side note the // list is a complex search that does not fit into any category.
