Is there no Good image viewing and managing software ?

I can't find software that fits this criteria

1) folder tree structure ala windows explorer. Along with that, should
come right and left click drags to copy and move files to other
directories

2) Tagging. Sorry, I don't want to keep my hand on the control key
while I select files - I want to go into tag mode and then click away

3) If I'm moving or copying a file to another directory and a file
with the same name exists, I want to see the images involved before I
just select replace

4) raw image support ie canon

XNView has a great interface but has no tagging feature whatsoever
which is unacceptable. I just tried copying files with a drag and it
give me some weird error - on a file copy no less. Unacceptable

Faststone - quick good, but file replace/overwrite does not show the
files involved. Has tagging which is pretty good although being
picking I would like a larger area to click a tag on a file. No
dragging of files ala explorer. They don't answer their emails. I have
emailed twice, about 6 months apart, and am yet to hear a response

Irfanview - just don't like it. Doesn't have the same nice interface
like the above 2 programs

Thumbs Plus - don't like messing around with thumbnail creating (might
be a way to turn this off). No drag copying but this program is pretty
good. Tagging is kludgy - a tiny flag indicates a selection and you
have to hit the insert key. Viewing tagged files is buried in a
menu....No so professional looking interface with a cheesy thumb icon

ACDSee - would love to try the latest version but it crashes on my
main comp. I have used older versions which seemed quite good

Is there not a program out there has nice tagging, an explorer like
interface, drag and drop copying/moving, shows the files involved in a
file replace /overwrite and has support for raw images ???

any input appreciated..

best regards
