P: Allow Lightroom Classic to move the filmstrip into a vertical position.

It's a feature in CaptureOne, which is why Adobe won't implement it in Lightroom.

Johan W. Elzenga, great tip. Thank you.

You can't, but there is an alternative that works quite nicely, especially on an ultrawide screen. First, make you main Lightroom window smaller than the screen. Leave a 'gap' on the right side. It means you need to drop out of any type of semi-full screen mode. Next, activate the 'Secondary Screen'. Most people think this option is limited to two real screens only, but it is not. You can open it as a window and place it anywhere you like, even on the main screen and even if you only have one screen. Obviously the secondary screen should also not be set to full screen mode to make this work. So resize the secondary screen window to fit the gap that you left open on the right of your main window. Now you have a 'multi-row film strip' on the right side.

There are lots of flexibility in the LrC Display you can collapse, top, bottom, left an right panels. When they are collapsed and you hover over the triangle to display or click to expand.

LrC is an Alternative to Bridge / Camera Raw trying to get one to function like the other will only lead to frustration, make a choice.

The filmstrip can be switched to vertical in Camera Raw, but that isn't an option in Lightroom.

Hi I'm sure I saw someone demo how to move the filmstrip,which is horizontal by default, to a vertical position. Wide screens mean you have lots of width but not so much height. How on earth do you do this? Rgs Andrew
