[Evolution] Bug#429682: Deleting columns in message list is too easy

[Alain Kalker]

Package: evolution
Version: 2.10.2-1
Severity: wishlist

--- Please enter the report below this line. ---

When trying to change the sorting order or the width of columns in the
message list, it is too easy to accidentally delete them, in particular
when using the touchpad on a laptop. I would like to suggest one or
both of the following:

- make Evolution less sensitive to dragging a column heading off the
  heading bar, so it doesn't consider accidental dragging to be a request for deletion of that column.

- show a confirmation dialog when a column heading is dragged off the heading bar.

Cheers,

Alain
