I was trying for a few hours trying to round border to the stickies.
I did manage to have a round border for the sticky in the end but I realize they look real ugly with round border (especially when collapse, looks like a capsule..haha) and the codes I trying is still buggy, which makes the stickies 'swim' down the screen when they are collapsed, so I decide to remove it away first since they sort of make the stickies look weird =(
Also, solved some bugs for the current implementation and also added the notification codes so that alerts can be set. I am not sure if there is a better way, but it seems that all the example I found sort of uses the 'brute force' way of setting up notifications - A timer with an interval of 1000 and on each tick event, loop through the array for any alarm they have. I try another way instead, althought I believe there should be a much better way..haha.. for me, I keep track of the next incoming alert and set the timer Interval equivalent to it. Whenever a notification event occurs, or a notification event is added, I loop the stickies and find the next nearest incoming notification again, and reset the timer Interval. It works fine so far, maybe i try to run it on VM and change the system time on it to see if anything crops up tomoro.
Anyway this is the screen shots of the current implementation:

Manage to add in color picker

Changed the icons (I know it looks familiar) Anyone can volunteer to make icons ? ha..

I know it look weird, removed
Resizing is now smoother too, thanks to serena for supplying her goo-codes..haha.. will touch more on that tomoro..time to ZzzZ
Hopefully will have time tomoro to do up all the little little bugs.
