For a specific reason I have added SumatraPDF as a PDF viewer and assigned it to a shortcut.
Normally the F9-viewer would be fine. However, in some cases I prefer to have Opus launched twice separately, side by side and reorganize files from 'left Opus' into sub folders in 'right Opus'.
This way I avoid the tree in left jumping up and down.
(I am sure there are better ways, but this works just fine for me)
Drawback, however, F9 preview pane is too small.
As for reorganizing PDF's, I have set ctrl-F9 to launch SumatraPDF (free, portable) showing the contents of the file in a floating window and allowing me to zoom and rename it, if necessary.
(Technical point: There's still only one Opus running, it just has more than one window open.)
If the only reason to open a second window is to have two folder trees, you can do that from a single window. Lister > Dual Folder Tree, in the menus, if it's only something you want temporarily. Preferences / Folder Tree / Options / Open second Folder Tree in dual display mode if it's something you want all the time.
Do you mean you want to have everything on the F9 key, and something (another key? toolbar button?) which changes what F9 does between opening the viewer pane and opening Sumatra as a separate app? Or something else?
Thanks for the reply. As for toggle: I meant to say that with ctrl-F9 SumatraPDF opens the selected file and ctrl-F9 again would then close it, i.e. similarly to the current F9 FileView-behaviour, i.e. F9 Open FileView, F9 Close.
SumatraPDF shows the file in a larger, floating window,
also I can copy text to clipboard then,
F2 allows me to rename the file and use the clipboard text as a part of the name, so it is clearer what the file is about.
Regretfully Acrobat does not allow renaming 'open' PDFs..
Wish this would be available in Opus.
(Vainly searched for it)
Opus has an @ifrunning code which lets you run different commands depending on if a process (e.g. SumatraPDF-3.4.6-64.exe) is running or not. But you would need to find a way to tell Sumatra to close its window (or use the AutoHotkey approach WKen suggests).
