The release 0.5 of Ielig Calc, the native spreadsheet, is in the Store now.
As described above there are many improvements.So you can now create .ods files readable for e.g. Libre Office Calc.
A last minute change offered a smaller header for landscape orientation on phone or tablet. Please remind the support for “real” keyboards, there is a setting for keyboard arrow keys.
Thanks for testing, especially to Ladislav.
