List watcher tickets in user profile
Please create a new tab underneath Created Tickets named Tickets.
This new tab may include Requester, Watcher and Technician assigned tickets.
Unfortunately the Created Tickets tab only lists tickets the user was a requester for and fails to list tickets they watched or was technician of.
This is often an issue for me when a manager requests that John Smith is to have something like a new workstation. The manager is made the requester and John Smith is made a watcher to ensure his also informed. In the future when we want to list John's tickets via the users profile, no ticket for his new workstation appears as he didn't request it.
This new Tickets tab would behaviour similar to the Problem and Changes tab which already exists in user profile.

Cutomize tooltip - autoclose parameter
Disable autoclose for the tooltip on users - Add user customization? This may allow to freeze the tooltip when viewing a ticket.

Add "Addociate Myself" Quick link to Default Items To Show and Ticket Timeline
I love the quick link to "associate myself" in the ticket tab. If it could show up in the timeline and become in option in the default items to show in the assistance tab, it would make it easier for technicians to grab tickets.

Propose Entity @ login
First thing to propose when a user logon to GLPI : Which entity would you like to open ?

Don't ask for login in the survey
The ticket survey are send to users, but they can respond to the survey because it is asking to login in GLPI. It's possible to open the survey without asking for login ?

Plugins menu: different coloured buttons for enable/disable/install/uninstall/clean
See http://forum.glpi-project.org/viewtopic.php?pid=315604
The background colour for all these actions is currently the same. It is hard to see "at a glance" what the status is on a long list of plugins. (Especially "enable" vs "disable")
Differentiating by colour makes it much easier to see status.

Printing Ticket Details
The print layout of tickets is unusable at present on latest version, would love some way of printing and selecting the info you want to print of an export option on individual tickets

Past-due tasks disappear from 'Your planning' view on home-page
Hello
Could it be possible to show 'past-due' tasks on GLPi home-page in the 'Your planning' place?
As of today these past-due tasks are not appearing anywhere.
This leads to forgotten 'to do' tasks.
Thank you,

Working days
Hello!
We have been issued with some holidays which can be transferred to another (working) days.
Let me explain with an example.
In Russia we have a holiday on 23 Feb. So we have 3 days holiday:
Sunday(21), Monday(22) and Tuesday(23). But in this case we should work
on Saturday for Monday. And there is no way to transfer days or make
weekend days working.
So please add a feature like a "close days" but with reverse functionality.

Auto close for ticket where no reponse is received fromt the requester
A feature that would allow the auto closing of tickets after a preset time when no response is received from the requester would enable the automatic management of tickets waiting for input.
This would be used where a question has been asked by the technician to the requester to complete an action and comment or where input on the current status has been requested. I have situations where a requester will never reply and the tickets have to be manually cleaned up on regular basis.
Companies such as Google Support use this type of feature as a standard part of the ticket handling.
