Sorry to bother you with an El Capitan bug, but maybe it's good to have a heads up regarding this glitch.
On OS X 10.11 El Capitan (Public Beta 3, probably 4 as well, will check today) and CC2015 Indesign, when you open the place-dialogue and search for a file, the little UI-bar that lets you refine the search to a a specific folder ... is gone. On all machines running 10.11, on 10.10 everything is fine. The bar is missing in all possible view modes (files, thumbnails and so on).
Just wanted to share this, maybe Apple or Adobe will fix this glitch in an update.
It won't be seen by the right people by just posting it here.
If you're doing the public beta, use the Feedback mechanism to pass it to Apple.
For Adobe, use this web page:
