Visibility of attachment upload

Hi,

I've noticed that when uploading an attachment (after you've selected the file) to a Task, it takes a while (especially in the field) before the screen pops up showing it's uploaded.
Because it's not visible that Fewzion is uploading it and it's taking a few seconds, the guys think that their attachment is not being uploaded. They either start doing it again or are confused why 'nothing' is happening.

Would it be possible to show some sort of egg timer or pending circle of some sort that makes it clear that Fewzion is uploading the attachment?

Thanks
