I love the new property panel but hate having to expand it out each time I need certain controls especially alignment, and pathfinder tools which I use all the time. Photoshop expand them inside instead of an external window or popup. it's also smaller because it's not duplicating UI elements. Also both Animate and Photoshop have the ability to collapse property groups that you don't need to allow for a more customized experience.

Regarding my previous comment, the Transform panel shows the options for live shapes as desired. It is a little confusing since these options are labeled "Rectangle Properties", "Ellipse Properties", et cetera and that is why I expected them in the Properties panel rather than the Transform panel, but having them visible by default is better functionality even if the panel name is a bit of a mismatch.

Besides the type work described above, when working with live shapes it would also be much better to have the ability to edit their options readily available in the properties panel rather than have to click the ellipses to see "more options". The user should be able to choose to show them by default rather than have them hidden.

Window > Control ...is what you looking for!

The new design where you have to click on the properties panel, and then click the ellipses to see other options is cumbersome and slows down my workflow significantly. Instead of hiding tools underneath other tools, there should be an option to leave these ellipses open at all times. Very frustrated that in order to change border radius through the properties panel, I have to click on a tiny "more options" button when the options should just be there in the first place.

When an object is modified somehow, for instance; blend or type on path, always show the options. Preferably in the properties panel. Use a hierarchy for these options when there are more.
Options and properties in illustrator are hard to find. That is why I still do not like Illustrator after more then 25 year of using Adobe products.

Please include an option (by right click perhaps) to have certain areas of the properties panel's "more options" to always show.

Specifically, right now I'm doing a ton of type work and having to click the ellipses every time I need the rest of my character settings is incredibly counter intuitive and getting to be really frustrating.

Thanks you.

Thanks for reporting the issue.
I got your issue and right now there is no way to open it automatically in Properties panel when the live shape is selected.
However if it is hindering your workflow you can use Transform Panel.

When you have a primitive shape selected in the properties panel there are three dots which allow you to edit the shape attributes eg pie angle if it's a circle. I can see no way to have that panel open automatically why is it always hidden behind the three dots button? I'm constantly having to click to open that panel.

It'll be great if the More Options (the three dots) appears automatically when passing the cursor, so it's less clicks to do, so is a faster workflow.
