Integrate Instant Messaging Server (Openfire - Spark)
Integrate GLPI with Openfire Instant Messaging Server and Spark client, both are Open Source projects:
Openfire is a real time collaboration (RTC) server licensed under the Open Source Apache License. It uses the only widely adopted open protocol for instant messaging, XMPP (also called Jabber). Openfire is incredibly easy to setup and administer, but offers rock-solid security and performance.

Spark is a Cross-platform real-time collaboration client optimized for business and organizations.

Integrate Simcard plugin into the core

Support for Detailed Printer Page Counters by Paper Size (A4, A3, etc.)
I would like to request support for detailed printer page counters by paper size in GLPI. Currently, only counters like copyblack_a3 and copycolor_a3 are supported, but I need counters for other paper sizes (e.g., PRINT_A4, PRINT_A5, PRINT_FOLIO, etc.) for both printing and copying functions.
This feature was discussed in the GLPI Agent GitHub repository, where I provided snmpwalk data for a Kyocera TASKalfa 3011i printer, and it was confirmed that GLPI Agent can collect this data, but GLPI itself requires a significant update to support it. Here is the link to the discussion: https://github.com/glpi-project/glpi-agent/discussions/913 (note: the issue may have been moved to "Discussions" by the time you read this).
I believe this feature would be useful for many users who need detailed tracking of printer usage by paper size.

Option to assign entities to groups or add field 'location' to entities and search tickets by this criteria
Add option to assign entities to groups(regions, routes or something) or add field 'location' to entities to sort ticket for easily plan route for car (technician).
We have many customers (200, one customer-one entity) and always 100+ opened tickets.
Searching and planing tickets from one region(route) is hard. There is no easy way to select ticket from one region(location) to plan best way for car/technician.

Import and Sync planning GLPI side
Hi,
A function to import ical to GLPI and another one to sync GLPI planning from another planning could be great.
Thanks

Custom welcome page (group view, global view, etc...)
We need to be able to customize the display of the front page for users
The 3 views (personal, group, global) are not usable.
Pls add the ability to filter / add columns

Integrate PDF plugin
Being able to print in PDF in GLPI out of the box is an old request from the community :-) !
