Adding to user lists is too slow and clunky on the new Title pages.

I'm talking about the new Title pages sneak peek: https://community-imdb.sprinklr.com/conversations/imdbcom/title-pages-new-version-available-for-sneak-peek/5fc7eae5ce4ce1357af24f6d

Very often I add to the Watchlist, and immediately add to some of my custom Lists (like a separate one for the stuff worth watching together with my family). This simple experience became so much worse and degraded on the new Title pages. 

Before, you could just add to the Watchlist and hover the cursor to add to a different List via the Dropdown. It took about 2 fast clicks, the Dropdown appeared immediately. 

Now, you have to click on add to Watchlist, then explicitly click to the down arrow, then wait for the Popup to load, then wait for all the Lists to load with the loading animation. The slower the machine/network is, slower the process. You can see for yourself by setting Slow 3G Network throttling in Chrome Dev tools, it becomes almost unbearable. Why can't it just be cached or preloaded, like before? At least the last 5-10 used Lists.

Also, I understand the need for a modal Popup due to mobiles, but the Dropdown would be so much faster, since it won't interrupt the flow. The current down arrow even implies for the Dropdown. The Dropdown could be a fast small list on hover (only PC can do hover), while clicking still could lead us to that new Popup. That would make the experience so much sleeker. And eliminate the issue when you opened the Popup, but can't add to the main Watchlist from there (and won't even see whether it was added, if the screen is small). That is confusing cause the Lists Popup UI is very similar to the mobile app, but the mobile app has the default Watchlist on top of it.

I often use the iPad, and the iOS IMDb app experience was very nice once I realized you can access other Lists by long-tapping the "Add to Watchlist" button. But since you're trying to make the website mobile-friendly, it is very strange that the List functionality can't even fit on the screen anymore. My iPad is a pretty common one, 9.7 inches 2018 (6th gen), I guess the larger ones wouldn't have this issue. But when I open the new Title page in Safari, it's just cut short cause the Lists button was moved to the very bottom and doesn't fit there. I'm attaching a screenshot. Even once the yellow top bar will be gone, the button still wouldn't be able to fit. The issue could be fixed by allowing it closer to the poster instead.
