My problem too with loss of visual editing features.
My configuration:
Wordpress v 4.6.1
TinyMCE Advanced v. 4.4.1
Wp-pano v1.13.1
PC Win10 64 bit
Browsers: Firefox or MS Edge
Enabling WP-Pano leads to loss of visual editor features when loading a page for editing
Disabling WP-Pano and purging browser cache leads to recovery of visual editor features
reinstalling wp-pano and WordPress 4.6.1 did not help.
