How can we improve WHMCS?

In admin area, it is a little discomforting to have to replace commas with dots while inputting decimal values, in particular when having to copy and paste between systems that respect proper internationalization. My proposals are

- step 1: at least accept comma separated decimal values by performing a search and replace in input fields, like prices
- step 2: perform full transformation in input and output between internal dot-based representation and admin area selected language locale settings, like what is done with dates.
