Hello, Please would someone have a look at this enhancement request?
Given a columns definition like this: #+COLUMNS: %50ITEM %5Effort(Hours est.){est+} if the property :Effort: contains time values in HH:MM format then the {est+} summary type doesn't work because it requires a real number ('1.1') or a range of reals (e.g. '1.1-2.5'). There are already functions in org-colview.el that convert between string of HH:MM and numbers. I am gradually learning elisp and have recently taken a long time to achieve something fairly simple so am passing this one along! Thanks, Myles
