Not sure if this is in the right place but,
I often just scroll and browse through hacs looking for juicy stuff.
Every time I open an add on, view the details and screenshots etc, when I go back I have to open the list of available addons either integrations or frontend and start scrolling from the top of the list again to where I was last.
Would be great if it took me back to where I started off and I didnt loose my place every time I opened one 
Not to nitpick but since the HACS author is VERY clear in the install instructions that HACS doesn’t contain add-ons I feel the need to correct your terminology.
HACS doesn’t offer add-ons. It only offers third party integrations, front-end stuff, etc.
You FR is valid but you should correct the terminology to minimize the confusion to other users.
Closing. HACS is not a core integration. Please open a feature request on the third party developer’s github project.
