underline post list entry title on hover

[vindex10]

I would very much like to be able to make the "hover" more explicit than just changing the cursor to "pointer", on the list page, when hovering on some entry.

I suggest to underline the title:
#1402

But maybe there are alternative suggestions and we could land on something together :)

Thank you!

Closing as this is an amend for #1401
