Short description
We should disable the navi bar action AddLink for pages which are defined in the navibar.
- Why? nav_bar links are admin configured (and can also get removed by admin). quicklinks are per user (and maybe you don't want to lose that link if the admin removes it from the cfg).
Well the navibar does not change if you like to add a navibar link. It looks to me that it is easier to explain "You can't add quicklinks for existing nav_bar entries as well as you can't remove one. It is only for your personal links." I think it is much easier to add the link at the time some admin removes it.
- Well, I think that feature would not be useful at all. If someone adds a quicklink and then notices that he (currently) has a duplicate to navibar, well, then he'll just remove it again. As there is no harm related with that, there is no need to specialcase and prevent this using additional code.
And how should that happen, you can't have dubs with current code. It is only a small useability problem.
- You don't see the duplicate, but internally it is there. Thus, you also can remove it again. Or you can keep it for the case the admin removes the one from navibar some day. It just does not matter.
