Unfortunately, it is hard and we are as frustrated as you are, else we would have done it a long time ago. The good news, we've made some changes in the background which will help, so bear with us for a while longer.

Any update on this?

This is also an issue within a project. For example, the Files tab of a project also has non-functional sorting. It's really a mystery why the functionality seems to be there but is turned off.

Come RWS/Trados, this surely can't be this hard to implement since the majority of columns have the sort feature there but ts disabled so why can't it be enable for every single column in every area???
