Viewer Pane command to open on the 'working' side of the lister that has focus

I'm finally utilizing the magnificent Viewer Pane to visualize .pdf covers/contents - -
my standard lister is 2-pane vertical -
and the Viewer Pane seems to always open on the far Right of the lister -

is there a command to make it open on the 'working' side of the Lister -
or the side that has caret/cursor focus? I suppose that's like asking
"How to make the Viewer Pane open on the Right side of a Left Dual Pane Lister?" :crazy_face:

I tried both Set VIEWPANE=Toggle,Vert & Set VIEWPANE=Toggle,ToggleLayout
but neither worked for what I want.

Also - if I can hitchhike on this question - what kind of setting would show actual pdf cover images for multiple files in the folder - I clicked on Thumbs which obviously displays the Acrobat pdf icon in my case - but can each actual image be displayed? If I could just see them all at once, then I wouldn't necessarily need the Viewer Pane to see them 1 at a time.

No, I don't think there is.

It's not a setting, you need the right thumbnail maker. I use Sumatra, which gets thumbnails for most of my .pdf files.

Thx - all try Sumatra - and as a further idea - can it simply show the actual cover image
upon mouse hover over the filename? guess I'm about to find out

ha ha! - As I surfed around the giggle hit list, I found none other than the Resident ! Thx @Leo!

I came across discussion on a Reddit thread:
https://www.reddit.com/r/Windows10/comments/wf34qs/is_there_any_way_to_get_pdf_previews_as_file/

that pointed to Leo's fix that matches my situation:

I run Acrobat XI Pro (32-bit) on w10/11 64-bit.

So - a couple questions more for Leo, perhaps? -

  1. Any way to speed up the thumbnail rendering? or ... once rendered, do they cache?
    And if they cache, is there a specific maintenance to observe with the cache?

  2. is there any other way to have files set as < Details >, yet be able to just hover on the filename and get a pop-up image?

Using a different PDF thumbnailer is the main way, if the one you have installed is slow.

They'll be cached by Windows, the same as in File Explorer.

You can add a thumbnail to the PDF info-tip under Settings > File Types.

thx Leo -

I did add {thumbnail} under System File type >pdf > Info Tip,
but nothing happens when I hover - are there other things I might need to do?

Also notice that subsequent times changing from Details > Thumbnails are faster
for the same folder - just takes a little while for that 1st caching to occur.

Nothing at all? Info-tips may be turned off (Preferences / File Displays / Options / Info Tips).

What's the full into-tip definition you're using currently? It would normally have more than just the thumbnail.

Yep - I enabled that - now it works - now is there a way to make that tip larger?

also - a button I made to toggle thumbnails also toggles the Image toolbar on -
is there some code I can add to prevent that?

my code: Set VIEW=Thumbnails*,Details

I tried Set VIEW=Thumbnails,Details without the asterik but no difference.

Yes, see Info Tip [Directory Opus Manual]

It's all working as desired - Thanks again (& I'll single out the questions from here on)
