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.

Combine external links with Remote Management
A few years ago you added the possibility of being able to inventory the meshcentral, today it could be done with rmm, but in these years I have not seen that when it is detected if there is a remote management, it takes the hyperlink, since it is not a standardized link, So what I know is possible is through external links to put our administration and remote management page and pulling the data from the "$id" field that you generate in Item_RemoteManagement.php, since I wanted to do the same with the RMM but this It disappears because I don't know, so the most viable thing is to insert our page through external links: example:
https://mesh.net/?viewmode=11&hide=31&gotonode=$id
As you can see here, the meshcentral has the link enabled so I edited Item_RemoteManagement.php, but this becomes cumbersome because every time there is an update it is lost and I have to reconfigure it

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.

Problem displaying the interface on the combo button
When the string of the item "Group in charge of the hardware" is too large, overlapping the item in the next column.
See the image below:

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.

Dashboard it doesn't display in another browser

When I create a dashboard with a filter, it doesn't display in another browser, as if it were only saved for the browser locally. (sorry, the video doesn't show the screen of the other browser, follows the screamshot image)

New actions Business rules for tickets
It would be interesting if the business rules for tickets have these actions or change textual fields such as description, title, or ticket followup.

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!
