Dolphin change proposals

[todd rme]

I have a few things I would like to try to implement for dolphin, but
I before I get started I want to check to see whether people think
they are good ideas or not. They are (in no particular order):

Drag and drop support for the tab bar.  Currently dropping files on a
tab does nothing, which is inconsistent behavior.  The breadcrumb bar,
places panel, folders panel, and folders all bring up the "copy, move,
link" menu when you drop something on them, which is what I want to
have the tab bar do as well.

"+" button on groups (when groups are visible).  This would behave the
same as the + button on files and folders, allowing you to easily
select and de-select whole groups.  The reason that this would be
different than just clicking on the group header is that, at least as
I understand it, clicking on the group header would select that group,
de-selecting anything else already selected, in order to maintain
consistency with how clicking on files work.  But if you prefer
clicking on group headers does not de-select already selected files
then the + button would not be necessary.  I prefer the first case,
but will still be willing to implement the second.  I know selecting
of group headings is broken completely, I would need to fix that bug
first.

File count for groups.  This would just be a bit of text next to the
group name saying how many files are present in the group.  It is not
very useful for small groups, but I think it is useful when dealing
with very large groups of files that cannot all be seen at one time.
At least for me this has the same use as showing the number of files
in the entire folder in the status bar, as Dolphin currently does.

If you select multiple files of different types, then right-click it
will have an "open with default applications" or something like that,
and all the files will then be opened with their own default
application.  I am aware of the bug where files are often opened in
many duplicates of the same program (like pictures with gwenview) and
the one where files with different extensions but the same default
file handler are not opened by that file handler (this happens with
different sorts of text files, like .h and .cpp files).  I would have
to fix these bugs first.

And maybe an actions panel, which show the "actions" right-click menu
in a dockable panel for easier access and improved visibility.  It
wouldn't be present by default, but I think would be good to have
available.

I would like some feedback on which these ideas (if any) people think
are good and should be implemented or if there are any suggestions.  I
can't guarantee that I will be able to implement any of these, but I
will at least try if people think they are worthwhile.
