Integrate ticket survey plugin into the core
It is very disadvantageous to move to GLPI 0.90 when this plugin is activitated in a previous version and not up to date.

Add/link ticket directly to Virtual Machine (guest) under Computer (host)
Currently it is possible to add/link ticket only to computer (host) even though it's possible to list virtual machines (guests) underneath. It would be great to add/link tickets to those virtual machines (guests).
For example it could be valuable to know how many tickets/troubles are related to which particular virtual machine when looking for repeating problems, problematic VMs and similar.
Hosts could be mixed with Linux/Windows VMs and each of them could be managed be different person so assigning tickets just to host is not enough.

Support for Storage as category
By default storage devices like NetApp,Synology, Dell EMC are detected as Network devices, and it is not possible to see the disk usage, CPU and Memory usage. It would be nice to have it and be able to manage.

Add notifications for historical changes and global view for this
First of all...greate job with what you guys are doing. Keep working like that!!!
My suggestion:
Add the habilitie to notify via email about historical changes made in the inventoried actives. For example:
- Know when a memory RAM or drive or any other hardware component or software were removed from an inventoried active.
- Notify about this change
- A global view where we would be able to see these changes without enter to each actives one by one.

Integration of Microsoft Teams and Planner as a plugin.
Is it possible to integrate Microsoft Teams and Planner as a plugin or any other way? This would be very helpful, because Microsoft does not have a Ticket System in Teams and Planner - this could be a big chance for GLPI!

License management - not only for computers
It could be usefull to manage not only license for software/computers. For example license keys for appliance, network devices ect.

Implement ability to put operator in vacation mode
Dipatch operators don't always now people on vacation, and can assign tickets to them by mistake, a simple out of office checkbox, or even better a calendar could visually show someone that a user in on vacation (Like name in red in dropdown lists)
