Have you ever wondered why, after defining an alias like about-us for, say, node/123, your pages are still riddled with those ugly machine-generated tabs and links like /node/123/edit, node/123/revisions etc.?
Likewise for /taxonomy/term/% and /user/% links: did you expect to see /dries/track but got /user/5/track?
Do you find that your browser address bar also shows those ugly numbers instead of your aliases?
Have you ever been annoyed that upon clicking the Edit tab on, say, the about-us page, blocks that you configured to be visible on all about-us/* pages suddenly disappear?
In short, would you like your human-readable, SEO-friendly aliases to be carried through on all your tabs, links, Views, and blocks, on all your pages, not just on that single aliased base path?
If so, then this little module is for you.
