Feature improvements

Arrival Schedule

Following your feedback, we have implemented some great changes to make it even faster to build custom Arrival Schedules for your process. Included is the option to autofill time intervals (which can be customized to your schedule) and repeat after a day, a week or until the end of the simulation.

We have made changes to how you can access spreadsheets. Clicking the spreadsheet button in the ribbon will now show all spreadsheets and MDAs instead of the main spreadsheet. This greatly enhances the speed of navigating between different sheets in your simulation. We've also added a helpful favorites list to store your most used sheets.
