Enrique S. Vivar's dashboard

I have currently set the icons width to 80, which is the smallest value that
is accepted. My problem is, I have much more icons in the screen that can be shown.

How to solve this issue?
a) windoze allows several rows of the taskbar.
b) allow smaller icon widths
c) [my pick] have a "scroll" function so that I can scroll horizontally all the icons.
I actually hate when my Mail inbo, plus its corresponding 20 opened emails is hidden somewhere, due to other apps running, and I cant get to the icon!

d) Have a more granular control of icons collapse. For example, the mail app would show only the badge icon, plus all the email windows not shown......
