Im struggling to alter the Library panel on my interface. I want it to be wide enough to include both the description in the left HS, and icon 2 wide in the RHS. I can adjust the width of the panel but it simply reverts when I close the application. How can I solve this pleas, any answers will be rewarded with huge thanks and no money! Screen shot is what I would like...

OOOPS. screen shot is what I want to change....

Your best bet is to make your Library Panel free-floating, that way you can custom resize it any way you want. You do that by clicking on the tiny arrow in the very right hand corner of the panel and expand the contextual menu.

Select Floating and the panel will become a separate window, moveable anywhere on your monitor.

To open and close the panel, click on the book stack icon, right-hand upper corner.

I should have thought of that, any time I need it make it free floating, thank you so much..

You can use the ui "dots". Near the bottom left of the standard ui you will see a small square with 9 dots. It will say ui.

Set your ui to the way you like it then click on one of the dots and it will fill up. When you next start poser click on this dot and the ui will revert to the version you set.

I usually click on the first dot with the ui in default settings, so I can easily get back to this if I mess things up, and click on the 2nd to save my preferred setting

Something else you might need to do is under edit> general preferences>interface tab, click on the launch to previous state.
