[Plugin: Admin Collapse Subpages] Suggestion: Make the /- images bigger, please

Thanks so much for re-writing this plugin!
It seems like such a popular notion, but the only other version is the one that stopped being updated. So again, thanks for bringing this into the WP 3.0+ world.

I did prefer the large +/- buttons in the last incarnation, so perhaps this could be included in a future update?
