TODO:
* Bookmarks of a location should remember that location (addr, company, etc)
* Make SAVE reference current lat-lon center point WITH zoom level AND view mode. -cwf
CHANGELOG:
0.5? 2005-12-15 Rewrote the HTML generation and tweaked for 1.5/0.6.4 compat,
commented code a bit. -chris feldmann
0.4 - 2005-06-19 - Bookmarks now save "link to this page" location,
got rid of lat/lon input box (can do this from main search
box). Fixed bug with GM @include directive.
0.3 - 2005-06-18 - Make sure we're using a GM_setValue compat GM for bookmarks
0.2 - 2005-06-18 - Bookmarks
0.1 - 2005-06-17 - initial release
