Increase size of icons, taskbar etc...

Hi,

1) Using zorin os 8
How can I increase the size of the bar on the right when using mozilla for example ? its tough to select it (the bar which allows you to scroll up or down)
Or can I increase the speed of the rolling button on the mouse ? (not in mouse options)


2) I intend to put zorin lite on my old PC and put it in the living room so I can watch videos etc... while eating xD
The problem is the icons and the taksbar and the side bars will be very very tiny from a distance, can I increase the sizes too ? (maybe it's just about graphic card settings I dunno much)


ty :p

Hi the problem with that is if you reduce screen resolution (my first 'obvious' choice) is that once the mozilla firefox snaps to the screen, the scroll bar disappears off-screen, leading to the need to manually drag into focus:

S**t

Might look for some addons, some magnifiers or things like that, Under linux it should be easy to find, no ? :p
