Improve Sortby: lastmod with visual cues to help improve readability

[abuturabofficial]

When we sort out post by:

params:
Sortby: lastmod

Without any visual reference, the blog post appear randomly sorted.

What could be done?

1. Maybe show timestamp of lastmod instead of creation
2. More appealing approach would be to add a visual cue, Updated or Latest or something similar which conveys the post has recently been updated. That's why it's showing at the top despite the old creation timestamp.
