This is not possible anymore, or? (cancelling the calculation)...would be great.
I am looking for the option to use background transfers but at the same time avoid the size calculation. Can you add this as a feature request or provide an option to abort the size calculation - while at the same time using background transfers? ??

I just realized that you can cancel the calculation.

Thanks for your suggestion.

Have an option to Skip Calculation directory size

Sometimes you only want to download stuff without knowing how long its gonna take.
And sometimes Calculation directory size takes so long.. that i want to skip it for some times.

I know that i can disable it. But i want to skip it sometimes when it takes to long.
