Dazzle Configurable Switcher
I am currently using it only for a 1x1 brightness/ auto popup, which gives all the possible brightness options from a 1x1 space with good easy of use. Another advantage is being able to put as many buttons in a widget if you want. You can have 2 buttons in a 2x1 space, but also 3 or 4 buttons if you don't mind a smaller size. All those "1 huge 1x1 widget for each button or option" apps are really nothing for me.
Launcher Pro Plus
I use the Bookmarks, Contacts widgets and the Calendar (not much of a social web person). The widgets (you have to pay) are very nice as well. Layout is not fully to my taste, because they do not always seem very space-efficient for my homescreens, but their functionality is great
. Good payment and update options for those who can't buy it using the Android Market.
Launcher Pro
Again? Yes. No. The widgets in the paid Plus are nice, but the 'scrollable widgets' feature in Launcher Pro is what is seriously improving the functionality of homescreen widgets. Much information available, from the same amount of space
.
Android Agenda Widget
I have tried a whole list of agenda/calendar widgets, but liked these the most (together with Launcher Pro's widget). It's pretty space-efficient, showing me a lot of events in a limited space, while it's still easy to read everything at a glance. It looks nice and it's scrollable.
Okay, that's not 5, unless you count the Launcher Pro Plus widgets as single ones
. But these are all I use, I don't like having tons of widgets all over the place. If I don't know by heart where all the widgets are and what they do, I know I won't really use them.
