I'm preparing release v2.0 right now, I'm almost done, but the former clear hierarchy (standalone core lib outshine.el, dependent add-on libs outorg and navi-mode) has vanished since I turned them into a kind of 'org-minor-mode', now they all depend on each other and use each other. Breaking them up is not really an option. I would just need advice - if can make them all (require ...) each other without causing breakage? - or if I should rather make one of them require the other two (which on - the highest level lib navi-mode, or the lowest-level lib outshine.el)? >> (2) how to declare their dependencies as MELPA >> packages? > > I never used MELPA so I don't know.
