THank you for trying our PS module and thank your the feedback. If youre talking about exe, Installer just extract copies the modules to the selected location.
Since \Install-CVModules.ps1 file will import all the modules for that session and it doesnt copy to any windows powershell profiles. so you will not see it loaded after reboot.
If you want them accessible always, please copy them manually to create profile under system32 folder that lets all users to access it.
For the commandlet name change i will add this roadmap, and change them in future servicepacks.
if you have more questions reachout to me, i will send you my email
