Favorite or Custom Task Lists

Hi
We have several open ended tasks, which basically are running all the time, that we need to add time to on a regular basis (such as update/maintain Intervals - always interesting to see how much time goes into that).
As these tasks don't have an end date, and have a start date way in the past, they don't appear in the weekly/monthly view, so we always have to search for them or hope they are still on our recent tasks list, or pick them out from the tasks with no due date list at the bottom of the homepage.
Is there a way to mark a task as being a favourite, or sticky ... or something similar which would mean it always appears somewhere on the home page.
Ideally, i would like to be able to customise the categories of task that are displayed at the bottom of the home page (where currently we see "overdue tasks", "overdue milestones") and add custom collections such as "favorite tasks" or "admin tasks".
Is anything like this possible at the moment?

Regards
Cathy

One other item that might be worth a look is saving a task list filter than contains the tasks. If you run a filter on the task listing there is a save option at the very bottom of the list. Saved filters will return all of the tasks that match the criteria in a single click. I use saved task filters quite a bit to get at my common tasks.

Hi
Many thanks for the suggestions. Saved filters get very close to what I was looking for - in combination with the suggestion of adding a code or tag to the comments of the tasks I am interested in, which I search for in the saved filter. I have set up a couple of filters.

A couple of enhancements would make this work very well:

Tags
I am actually using a tag like syntax to mark up the tasks I am interested in, by adding the "tags" as a comment. Is there scope for actually adding a tag field, with tag pickers etc?
The ability to tag tasks, milestones, projects etc. would give users the ability to categorise intervals entities in any way they needed and not have to depend on the fixed categories of Worktypes, Modules, etc. If the filtering were updated to allow searching over tags, I think that would be a very powerful extension.

Include Saved Filters on the Home Page
Unless I am missing something (and the chances are high of this), if I save a filter from an advanced search, I can only access that filter from the tasks search page. There seems to be a different set of filters being saved when you save a filter from the Weekly page.
If I could choose to list any of my saved filters somewhere on the Weekly page (my default home page) - the combination of saved filters and tagging would be very powerful.

Just thinking out loud. I can definitely use what's there in the meantime.

Thanks again

Cathy
