1. i'm not sure which component is the correct, so i hope that this will be 
redirected to the right one
2. mostly this is for mswindows, but also for different windowsmanagers for *x

there is a need for more advanced file associations management.ideally this 
could be achieved by separate page in options.

it could have different files that are supported by oo.org listed. each would 
have two checkboxes beside - "change to open with oo.org" and "restore 
previous". then, when the user has made his choices he could click "apply" and 
these file associations would be changhed accordingly.

also it should include some presets - like dropdownlist with items "all", 
"none", "msoffice filetypes", "oo.org filetypes" etc. (for oo.org and restoring 
columns separate ones)

and the ability to add custom file types to the list (you can never be shure - 
maybe organization as one of securty measures will use internally sxx not sxw. 
ok, not the best example). anyway. users must be able easily through gui add new 
types that they could register/deregister for oo.org

this association type changer also should change file icons, too (and it should 
be able to restore them as well).

ps. this is _not_ meant as replacement for existing tools to modify file 
associations, this sort of functionality should be able to convert to oo.org and 
restore previous state not only for "open" action but also print. maybe others, 
but i think these two should suffice
