[Typo3-dev] Reasonable way to add more specific control for 'toolbar' of the edit panels

[tapio]

Hi

In  'class.t3lib_tsfebeuserauth.php'

each button has control, which base on generic permission right, for example

if ($perms&8) {...

I would like to add for FE editing additional conditions.
In FE editing could be nice to have button specific conditions.

In FE editing all buttons, which the user rights allow to use are just 
not required (some of them might even work properly).

User right -based control is not for me simple enough.

That was easy to impelment for 'alt_doc.php'.

But I don't have now any idea what to do with 
'class.t3lib_tsfebeuserauth.php'.

I would be nice to have control like the 'alt_doc.php' has:

mod.xMOD_alt_doc {
   disableDocSelector = 1
   disableCacheSelector = 1
}
