I'm not aware of articial limits, but be aware that by default all LibreOffice APIs are private and only a subset of those are available on the UNO API, which is available for extensions. It's a trade-off: once functionality is exposed on the UNO API, then that is meant to be unchanged, so improving that feature is more difficult once it has UNO API. (E.g. this is why extensions can't contain dialogs that load their content from .ui files.) On the other hand, sometimes a feature is not exposed on the public API because nobody felt the need for it; in this case once somebody steps up to do the work, it can be exposed. Regards, Miklos
