How turn on display of 2nd folder tree?

Hello, couldnt find the answer in the help file so..
When i click on the tab "Dual Lister" (or "Horizontal"), i get two listers each with its own folder tree. i like that. Then when i close one folder tree, it's gone! :open_mouth:

The ListerMenu item View : Folder Tree doesnt help here. Instead of re-clicking the "Dual Lister"-tab, is there any other way (button or keystroke) to display back the 2nd folder tree? i want it back, thanks! :slight_smile:

Using View: Folder Tree will re-open either tree if it is missing, if you also turn on Preferences / Folder Tree / Options / Open second Folder Tree in dual display mode.

If you don't want to turn that on, you could create buttons which explicitly turn on the left and/or right tree. (I'm guessing you just want to turn that option on, though.)

Thanks so much leo. I had the feeling that the solution would be that easy! (there are soo many settings in the preferences that i havent realized ..etc..)

shame on me. thanks again!!
