KDE4 : ark or something else ?

[NicoFr38]

Hi all,

I have upgraded my home computer to the latest kubuntu release with the KDE4 
environment.
For me (for the applications I use) everything works great
I use konqueror to web brows, Kate to web dev or to tcl dev, en Firefox to web 
debug.

The only thing that doesn't works as it was is ARK : no more right click 
integration, not supporting ZIP and RAR.

I know this is a known limitation, and justs would like to know how people 
that have upgraded to KDE4 deal with this limitation.

I have read about several solutions :
- use KDE3 ARK in KDE4
- use command line functions (that is what I do now)
- use an other app (which one is the better integrated and supports the format 
I have to deal with).
