I'm not sure I understand what you mean here; anyway I noticed that if you do a
search using the "Find file" (M-?) command, choose "Panelize" (at the bottom
of the "Find File" popup window), then change to some other directory (thus
exiting from panelized mode), if you now choose Left -> Panelize, you can recall
the panelized view of the last "Find file" results. Is this what you mean?

However this seems to work only with panelized results coming from the
"Find file" command, not with results from the "External panelize" command:
if I change directory, and then choose Left -> Panelize I get an empty panel.
Is this a bug?

In fact, that was more a help request than a bug report: I really can't make 
sense
of that menu item, so I think there's nothing much to "discuss", rather to 
explain
what the menu command is supposed to do.

Anyway, I did my homework and had a look at the source. 

The menu item is defined in src/filemanager/midnight.c and calls CK_Panelize,
which calls cd_panelize_cmd(), defined in src/filemanager/panelize.c,
which calls do_panelize_cd() (defined in the same file).

Unfortunately I don't know enough C and the mc codebase to understand what
do_panelize_cd() actually does, and there are no comments in the source code. :(

So I browsed the trac history of src/filemanager/panelize.c and found that
do_panelize_cd() was introduced in this commit:

  
http://midnight-commander.org/changeset/5c252726f1b52863a75b0118603a0e053923eded

which claims to fix this bug:

  http://midnight-commander.org/ticket/275

The discussion in the ticket deals almost uniquely with adding a ".." entry to 
the
panelized panel list, to get out of panelized mode; no references to the 
"Panelize"
Left/Right menu entry.

The commit message for the commit linked above in fact claims:

  "added menu entry Left\Panelize, to restore panelized panel"

but I still can't understand what "restore panelized panel" means
(indeed: all that command seems to do is to show an empty panelized panel).

So that's all the information I could squeeze from the source and trac.

I hope some developer can have a look at
http://midnight-commander.org/browser/src/filemanager/panelize.c
and explain what cd_panelize_cmd() and do_panelize_cd() do.

I believe you opened a ticket for this. Please also link to the ticket
or we'll have two crowds discussing this independently and therefore

Help: meaning of the panelize command in left/right menus

[cri]

Hi, I can't find any information in the internal help, or man page, or wiki,
about the "Panelize" command in the "Left" or "Right" menu.

I suspect it is related to the (well documented) "External panelize" command,
but when I select it, I'm left clueless with an empty panel.
Now what?
