It would be great to integrate an option to just record your own voice while speaking in a group. 

This would make dualvlogging in UHD Mode so much easier - atm Dualvlogging in UHD is not really possible 'cause your group members voices are too quiet on the recording. So, the only way left for dualvlogging - is to turn on normal-mode and get all that ugly interferences. If there would be an option to just record your own voice while using the intercom in UHD - every mate could record his or her own voice - after that, we just need to syncronize our samples of the cameras in the postproduction and the sound of all groupmembers would be great. for dualvlogging. There would be no more cutting and individually volume adjusting of the groupmembers voices again.
