been using 0.7.1 for a little while and finding it great way to organise
and search my usually disorganised notes.
I use shift-cmd-M (paste selection into a new slip) and using spotlight to search. Slipbox does more than this, but this is the feature that really saves me a lot of time.

If you havent tried this app and want something quick then give it a go.

Spotlight seemed to have stopped working for me on 0.7.2 though? - reverted back to 0.7.1 and I'm happy again.
