It would be great if you could utilise mathematics and functions while entering in your data, for example:
When using the "Add Line - Direction" function to add lines one could just simpily type in the bearing input box "65.4503+8.1505" meaning 65deg45'03" plus 8deg15'05" and the resulting bearing would be 74deg00'08"
Likewise with the distance one could apply a scale factor or whatever they require by inputting "1000.000*1.000168" which would result in a distance of 1000.168.
I would like to see all basic mathematical principles to be enabled such as +-/*() etc.
