It will be useful if you add a tab "to-do" (for example after the tab page Tools) in all objects displayed by dude.
A to-do entry coud have these fields:
1. date created
2. description of work
3. expiration date
4. flag if it is done or not
Then we could have:
- a notification if a to-do entry is near expiration
- a list of all to-do entry not yet done
The usefulness of this thing is obvious: how many time we forget a cable to be replaced, an antenna to be repointed, a device to replace etc, etc?
