FYI in case it's helpful, there is a setting to show more sites (but it probably wouldn't have scrollbars) https://matomo.org/faq/how-to/faq_23986/

We would likely not show all websites since some have eg Matomo running with 40K websites etc. and it would make things very slow even just to load that data. We could potentially show something like 9 of 40 sites or something else though.

I'd love to see the website drop-down be customizable. I have a few dozen websites, but I often find myself checking on just a few of them. It would be nice if I could re-order the list so those are at the top.

Workaround: As the list is A to Z, you can prefix the site name with a number that would sort the list displayed in the dropdown...

Unfortunately I ran into some trouble when trying to replicate this (couldn't add 15+ websites), could you share how it currently looks when you have many websites?
Just to check, we're talking about the dropdown element in the attached screenshot right?

Seems like a decent idea to have it have a scrollbar if many websites are added. Thoughts by you @Javi-Ormaechea ?

@Stan-vw I agree with making it scrollable, and keeping the search field to get quick access to a site that might be found at the end of that list. Another thing we could do, is to provide a list of the last 4 viewed sites so that users can quickly get back to those if needed, something like this:

@heurteph-ei That wouldn't help, as the list still only shows the 15 oldest sites. If you have more than 15 sites, there is nothing you can do to get the newer ones on the list, apart from deleting older sites.

Note that the site selector is also used on the Manage Users page (located under Administration), but this list is missing the "All websites" link, making it even worse usability.
