Implementing a calendar within UR?

[tmasters]

I'm playing around with the creation of a personal calendar in UR. Obviously, UR can be used to organize such hierarchical relationships, just as I have used plain-vanilla outliners to do so in the past.

Is anyone else doing this? UR clearly has a lot of power and dimensions beyond that of outliners, so I'm trolling for others' creative insights and/or implementations. Alternately, are there other programs whose calendar functions work well for you *in conjunction with* UR?

I could also use some help: I haven't yet figured out how to maintain a list of child items - days of the week, in this case - in a desired order (Monday, Tuesday,...). My attempted solution is to add a column for chrono order, so I can associate each day with a number 1 thru 7, and then sort on that column. In trying to implement this, I've added the column (of type "number"), but have been scratching my head as to how to actually enter the appropriate numbers. I haven't discovered how to edit or input such data. What am I missing? I'm guessing there's some way to have the attributes of choice show up in the Item Attribute pane, where they can be edited just as the current attributes can. I just haven't discovered how.

TIA,
