Google Calendar is definitely one of the coolest online calendars and task-management applications. It has everything an average user may wish for: speed, non-cluttered design and lots of useful and never failing features, i.e. calendar sharing, quick event entry, follow-up reminders (SMS/email), RSS feeds, etc. [More on Google Calendar...]. In addition to it’s standard feature set, there are hundreds of a user-created browser addons (mainly firefox) and problem-specific tips making it even better and more flexible productivity tool. Below, I have listed some of the better ones, if you’re Google Calendar user (or thinking of becoming one) than check them out.
FIREFOX (Addons and Greasemonkey Scripts)
(1) Better GCal - extremely handy extension that integrates bunch of must-have features into your Google Calendar. These are: (1) ‘To-Do’ box, (2) current time, (3) option to quickly hide Header/Sidebar menus, and (4) auto-connect via ’secure connection’ (see screenshot below nr.2)
(2) Extra Tabs (Greasemonkey) - replaces ’standard’ date range tabs with any number of customized tabs. Leaving it on default setting keeps existing tabs untouched and adds “Next 3 Days”, “Next 2 Weeks”, and “Next 3 Weeks” view tabs. (see screenshot below)
(click to enlarge and launch it in a new window)
(3) Google Calendar Integration (Greasemonkey) - integrates Google Calendar agenda into Gmail. See demo [More Gmail Tools]

(4) Forecast (Greasemonkey) - adds a small, draggable and expandable ‘Forecast’ box to your browser that shows next seven events from your Google calendar. (To get it running, you’ll need to provide it with your calendar’s XML feed, which can be accessed via ‘Settings->Calendars->select desired calendar->Private Address: XML’)
(5) GCalQuickTab - switch between Gmail and Google Calendar using keyboard shortcuts: ‘g’ for Gmail and ‘i’ for Calendar.
(6) Some more…

I am aware about Calgoo. I have plans to incorporate one more section to this post: ‘WebServices and Desktop Apps’, so I kept it for that. At the moment, I am only half way through it, and will need a week or two to complete it. I’ll definitely notify all readers about this update.
Thanks.
