If i drag US and put it to done column, system will start to process this action but will not finish, US is in column done, but without status done and after refresh flexboard move this US to first column type - in progress. Its US with tasks. If i use select from US card and choose done, it will change all tasks status to done and US will be also done - and thats what we need with d&d function.

If d&d works like this, me and at least two teams will be really happy and it will prevent us from chaoss in our boards :)
