Done for GLPI 10.0 with the Pending Reasons feature.

Both points have been addressed in GLPI 10.
1. The filters are now in a popover accessible from a single button at the bottom of the ticket view
2. Another button was added next to the filters button to display all TODO tasks in a checklist type of view
This is already in the latest release of GLPI. I do not know which version it was added in.

This is possible in the latest version (GLPI 10). I don't know which version it was actually added in though.
