Personal Information Management Revisited: Quick Do?

I am one of those (seemingly many?) people that migrated from a Palm device to a Nokia N8X0. Being a longtime user of the Palm OS platform, I grew accustomed to some things being built right in to the platform e.g. the Palm PIM suite (Calendar, Tasks, Notes, Memos, Contacts). Although all of the PIM applications were really nice, the one I always found myself using most was the Tasks application.

I always thought a Calendar was a little strict (and extremely time-intensive to keep up) for my needs, and something like a plain-text memo-like reminder was too far the other way. Tasks was just perfect. Structure with compromise.

When I first got my N800, I was disappointed there was no Palm Tasks-like application. I've tried them all, and none were up to the task (no pun intended).

Recently (actually, like just the last couple days) I looked into programming my own solution. At this point it is merely a mock-up: no data storage, no functionality, no killer features (or features at all), but it presents the concept of my ideas.

I call it Quick Do (and no, it may have the same Quick prefix, but it will not be integrated in Quick Clip).

Here is the proposed main view: (also showing future filtering options)


And the Add Task dialog:


The Date selector:



Will this turn into an actual application, probably (after battling with the gtk.TreeView widget for hours already, I would hope so!). But more importantly, what do you think of the interface? Finger-friendliness is out-of-the-question, but anything else? I have a laundry list in my mind of features that could be added, so a little direction is welcome.
