The Old TODO List

I'm starting reading the code of old Firefox Extension For Beagle.
I found a TODO List in readme.

- make install rule for installing to global extensions
directory (can be done without running mozilla?)
I don't think that is a good idea.
- need better icons
- only index content on initial visit to a page
- send HTTP headers to beagle-index-url?
Is it needed? HTTP headers don't contain much information about the content.
- remove context menu and preferences?
Create a new UI
- improve warnings
- call beagle-index-url with page title and mime-type
Good Idea, same for non-html files
- watch for beagle-index-url error and clean up tempfile
Is it possible ?
- save tempfile in safer place and with better name
Good Idea .
- include install.js for older versions of Firefox (<0.9)
- screenshot webpage
??
