- Please download and unzip the attached file.
- Copy the 2 files onto your device, in favour into the ThumbCal installation folder.
- Run the file "ThumbCalSPBShellReg.exe"
- Click "yes" to register the ThumbCal Plugin in Mobile Shell / Click "no" to unregister it
- Now a tap on SPB's now screen calendar or on an appointment should open ThumbCal on the specific date in day view
- There will also be shortcuts availabale in the Plannings menu:

• Calendar (ThumbCal)
  • New Appointment
  • Today
  • This Week
  • This Month

• Tasks(ThumbCal)
  • New Task
  • All Tasks

Please consider that this is an early beta.
A tap on "This Week" and "This Month" will open ThumbCal in the last view mode. This is a problem in 1.2.5 and downwards and will get fixed with the next release.
For the next release of ThumbCal I will improve the Mobile Shell Plugin to show ThumbCal's icons and maybe localized text.
