Disable new notifications after upgrade
When new notifications are created on a GLPI version, an upgrade to this version active these notifications.
For example, if you upgrade from 0.84 to 0.90, following notifications will be active after upgrade :
- New change
- Update change
- Resolve change
- Add task
- Update task
- Delete task
- Close change
- Delete change
- New project
- Update project
- Delete project
- Receiver Errors
- New project task
- Update project task
- Delete project task
This is the default behavior of GLPI : new notifications are active. If you don't know, our users may be surprised.
Please disable new notifications after upgrade.

Add an option to disable the bottom-right information pop-up
There's currently no option to disable the bottom-right information pop-up that pops when you save any modification in an asset or a ticket.
This pop-up is oftentime masking other important informations/buttons and is not really useful, 99.9% of the time it only states that your modification was successful.

auto-create ticket when contract expire
Add more possiblity to manage contratcs :
- add users/groups in charge of contratcs
- send notifications to the groups/users in charge
- auto-create tickets when contratcs expired, Ticket assigned to groups/users in charge

Allow to enable SNMP inventory features
Today in the SNMP inventory it is not possible to select whether or not to bring the resources it brings, such as: Model, Manufacturer, Description, Network Ports, Firmware, etc. There is something similar created in Administration > Inventory, where we can disable some resources We don't want to have the inventory of agents at all, but there is nothing we can deny partial import when we are talking about SNMP inventory.
My suggestion would be precisely that, allowing us to disable the partial import of certain SNMP control information.
This would be useful in the sense of, for example:
I have a scenario where the Network ports of the Switches that were inventoried are conflicting with the device's IP information and that's why I want to make my inventory "cleaner" and more "focused", so I disable the switch's network port inventory, the others data I want to have the complete inventory minus this one.

Users should be forced to select a rating for satisfaction survey, no default value.
When a user is reaching the satisfaction survey screen, the rating field is defaulted to 3 stars. Many of our users leave this field to 3 stars instead of providing a real rating. I think it would make more sense to have no default on this field to force the user to provide a relevant rating on his own.

Link multiple groups to an asset
It would be useful to be able to link multiple groups to an asset.
There are cases where multiple teams use an asset and having this possibility would be useful as we could have visibility of which assets a group uses and vice versa which groups use an asset. For example, during maintenance interventions, I can see who uses the asset and notify only those groups.
