More flexible matrixInput

[Beasterfeld]

Maybe this is already on the radar, but IMHO it would be more than a nice-to-have to have a more flexible matrixInput concerning

• Column types: It should be possible to have at least logical and character columns in addition to numeric and integer.
• Removing rows: Instead of removing the last row by clicking on the minus button the row with current focus should be removed.

Would like to have the option to disable the user possibility to add/remove rows. i.e. fixed size matrix true/false parameter

It would be helpful to be able to show and assign ROW NAMES, not ONLY columns, to the Matrix.
