Feature requests , thanks a lot for your suggestions! Let me answer in the same order.
1) We'll definitely put this feature request and consider it for the future releases
2) This one seems to be more tricky because it can potentially let you abuse the full control
3) We lock the sessions in case you joined when it was locked and leave them open if they were open before us. This behavior seems legit for us but we might be missing something and will appreciate your feedback.
4) We have this button, but only display it when connecting via the Unattended Access due to some technical difficulties. We are working on them and hope to introduce it in all the modes soon.
Looking forward to your feedback!
