The greatest flat file database ever. From Contacts to Accounts to home inventory etc.. make your own datafile of any kind i.e. Biz file - then load all the relevant info like Plumber, electrician, fuel oil company, all Medical contacts, Pharmacy / med records, etc. How about a file that you can keep a record of your purchases that matter, or a file to control your Craigslist sales. Keeping this info on your computer means your not Dead In The water when you lose your phone!
I've used Sidekick well before Sidekick 99. It's an excellent program, and holds the history of our activities as well as the directories of friends, businesses, etc. It has become invaluable, and we find it does work with our Windows 10. I would like to install it on our Android phones - any ideas as to how?
