icon/link for unread posts is too small

[vaklaff]

Hello

First things first: I'm a happy user of the forum and I thank all the people making it possible!

What would make me even happier? A much larger icon pointing to unread posts. The green arrow that is used now is too small:
   
This screenshot is taken on my computer where it's not much of a problem but on a phone it feels much worse - my fat clumsy fingers tend to hit everything except the icon :-)

For comparison, a similar situation at swissmicros' forum:
   
The round icons on the left, i.e. the largest things to click, are pointer to unread posts. No problem on a phone.

Can you please make this forum a bit touch-friendlier by enlarging the icon?
Thanks in advance!
