Today only Circus Ponies Notebook is on sale for 50% off at MacUpdate Promo, a very good bargain. Notebook makes an excellent piece of software for putting together trial notebooks and keeping a litigation notebook for each client-matter. A few of my favorite highlights: ToDos in your notebooks can be made to sync with iCal; the ‘MultiDex’ a supercharged index that automatically updates every word in your notebook and includes several useful stand alone categories such as ‘To Do Items,’ ‘Keywords,’ and ‘Due Dates;’ and, of course, the awesome outlining features which let you sort outlines by date, alphabetically, by priority etc. At only $24.95 it’s worth picking up just to have around.
