It maybe isn't beatifiull app but it's very good and brings new opportunities.
For example Amazon affiliate urls contain "tag" parameter which may be modified by adding your own value for that parameter or simply added into url.

You may also create custom CSS class and highlight any urls you like by your own CSS look.
 
Example:

https://www.amazon.com/dp/B01WSEEFBA/ref=gw_fr_desk_h1_sh_slp_apos_0079?pf_rd_p=565456y3-f7d5-4b98-a4e5-72ff4fdd68f6&pf_rd_r=9RY38PVVHBF63YEEXE It would change to that (with tag parameter):
