List of recently used Schedules (and their appropriate Catalogues) on startup
Working on a single Schedule (for your own studies) based on a single catalogue is much more difficult than it has to be: On every program startup you have to browse your documents for the Catalogue file and afterwards browse again for your Schedule file. A "recently used" list on startup, that automatically loads catalaogue AND schedule with one or two clicks, would be clearly more userfriendly.
