The new conditional formatting dialog is shaping up greatly. A particular improvement is that it is now possible to pick cell ranges in the condition and to enter formulas in the condition field. 

With this regard, I have two enhancement requests with regards to usability of the cell range picker:

(a)
To enter a formula in all usual spreadsheet operations, you enter e.g. "=sum(" and then you pick the cell range, e.g. C13:C15.
The new conditional formatting dialog behaves differently. In the field for the condition (in the dialog you get from "Format"-"Conditional Formatting"-"Condition") you first need to pick the cell range, e.g. e.g. C13:C15 and then you need to write the formula around, e.g. "sum(C13:C15". In case you enter the formula first, e.g. "sum(", it will be overwritten by the cell range picker. It would be good if the behaviour would be the same like in all other spreadsheet operations.

(b) 
When typing a formula in usual operations in Calc, e.g. "=s", then you get a tooltip telling you that the syntax for the formula is "=sum()". This tool tip is missing in the conditional formatting dialog. It would be good to have it there, too.

Thanks for the great work on conditional formattining!
