Knowledge base search - improve search filter module
The search for the knowledge base should be like the other searches for tickets / changes / problems with multiple selects and "NOT contains" etc. options.
Should give the possibility to search for example:
- Contains X but not Y
- is category X
- author is X
- last editor is X
- Associated tickets / changes / problems / projects greater than X
- last edited less that MM/DD/YYYY

Remote Desktop integrating Apache Guacamole
We use Apache Guacamole Remote Desktop to solve most of the tickets remotely, consider possible to perform an integration of GLPI with Guacamole Remote Desktop.
Glpi could integrate the Apache Guacamole Remote Desktop Web API to visualize the equipment, and insert a button in the standard interface in the details of the ticket to request the remote connection, which will open the browser to view the remote computer.
https://guacamole.apache.org/api-documentation/
https://guacamole.apache.org/doc/gug/guacamole-common-js.html
In the administration page of glpi, we could insert the user / password and the necessary data for the management of Apache Guacamole Remote Desktop.
Apache Guacamole
Apache Guacamole is a clientless remote desktop gateway. It supports standard protocols like VNC, RDP, and SSH.
We call it clientless because no plugins or client software are required.
Thanks to HTML5, once Guacamole is installed on a server, all you need to access your desktops is a web browser.

My Assets tab - visible at front page
It would be great if every user could see a list of all assets that are assigned to him/her.
List should cover all types of assets:
- computers;
- monitor;
- network device;
- phone;
- device;
- consumable;
- software/licenses.
This kind of list would be very helpful during inventory process where single user can verify what is currently assigned to him/her or what was assigned to him/her.
List shouldn't redirect to specific items (it shouldn't containt links to assets in the system) but just provide simple info about assigned assets.

Add Service Catalogue to GLPI

Better UI : hide what i don't use
A great improvement would be to make a modular IU: you only see what you use, or what you want to see. With an "edit" option to hide or show each part.
