great idea.

right now we only show the ProcrasDonate progress meter.

another idea is to show the meter that matches the category of the currently view page. PD if viewing a PD-tagged page, TWS if viewing a TWS-tagged page, and ....nothing if viewing a ? page.

ps - i would call this whole concept "Tag Mode", since it has to do with how sites are tagged. The full list I see so far is:
Sticky override mode
Sticky default mode
Continuous override mode
Continuous default mode

The override modes, unlike default modes, will change a website's tag, rather than defaulting to the appropriate tag for just ? pages.

In addition to Tag Mode, which is about tagging (or classifying) sites permanently, I see other kinds of Browse Modes:
Tag Mode
Temporary Mode - right now I'm ProcrasDonating, even if I visit TWS sites, but don't reclassify sites for good, just bundle up the time
SiteSquish Mode - ??

We track visits to particular URLs. URLs are bundled into URL_GROUPS (our technical names for these in the backend are even worse....). Each URL_GROUP can be tagged as PD or TWS. Finally, we keep track of totals (in time and amounts) for each URL_GROUP.

Currently we default to creating URL_GROUPS that encompass the entire domain, eg google.com.

Actually, we treat subdomains differently, so proudlyprocrasdonating.wordpress.com is viewed as a different URL_GROUP than procrastinateless.wordpress.com.

Anyway, expanding the flexibility of a URL_GROUP might be a great way to (permanently) bundle seemly disparate websites into a single concept (eg, the Go example in a different comment), as well as provide finer grained tagging (eg, treating google.com/reader as PD, but google.com/search as TWS)

we haven't implemented any of this yet.

heck yeah! we'll release simple graphs in a few days. keep the feedback coming and we'll iterate from there.
