We have a dialog ready [0] in evolution-kolab to ask for a user selection from several options they have to solve the conflict. However, this dialog is currently unused in evolution-kolab for the reasons you outlined (and the options set per folder without a possibility for the user to decide on a per-incident-basis how to resolve the conflict). Please see the dialog screenshot to get an idea of what would be needed (I've linked to the dialog screenshot to illustrate the use case). Basically this is * an informative text, with some background highlighting * a number of options for the user to choose from (the id of which to be returned to the backend), the conflict resolution strategy in our case (NB: this could be changed for a radio button list and the typical OK/Cancel buttons) * some setting to be applied to the folder configuration (whether to ask again for the next conflict or to keep the current user selection for the folder and not ask again) Maybe this helps ironing out the requirements for a requester infrastructure. Input fields may also be needed in some cases, although PIN entry is already handled (not sure what else would require text input).
