Possible glitch in KDE menuing (and other menus too) for Qubes disposable templates

[unman]

Then preferences must be set, including “template_for_dispvms: true”
FInally, to get it to show up in menus as a disposable, you need to set features, in particular “qvm-features [vmname] appmenus-dispvm 1”
The problem is, when I do this, it won’t show up in the KDE menu as a disposable. Nothing I tweak afterwards will get it to happen.

It is my experience that this will show the disposable:qube menu ,
and rename the original to Template (disp): qube

The only difference of note is that I use qvm-features [vmname] appmenus-dispvm True
rather than the implicit 1 that you cite.
