Now that I have a working messages notification extension to sugar's current notification system. I can follow the suggestions mentioned on trac [1]. One possible Idea: 1. Lets simply define a _PREEMPTIVE_SPACE_TRESHOLD (refering to jarabe.journal.journalactivity) where PREEMPTIVE_SPACE_TRESHOLD = _SPACE_TRESHOLD*1.5 . This is just an example, just replace it with your favourite formula. 2. When this PREEMPTIVE_SPACE_TRESHOLD is reached we can simply add a message notification on every startup. * Notification Icon appears [2]. * User reads the content [3]. * User can access information about the issue on the wiki [4]. 3. If the user still don't remove unnecessary entries then it will reach SPACE_TRESHOLD and the ModalAlert() will show up. We could also follow the suggestions on [1] suppressing the modal window when the journal is active, until enough space is available again. Suggestions or Ideas?
