I can understand this being used in a custom fork of OBV for developments but unsure if it's something that is applicable in the main release, as I understand it you're using it so you can quickly check on your boardview file generation ?

If it's felt that this feature should be added, I'd say it may be better to modify the existing Load() call such that if it looks for a flag to preserves the state rather than the separate loader. That way we don't have to remember to duplicate code for any new file format being added in to the Load call in the future.

Yes, the feature is mainly meant to make the development of exporters easier. But seeing that it isn't a difficult to understand feature I thought that adding it to master wouldn't hurt.

That being said, I already refactored the code so that ReLoadFile() is now integrated into LoadFile(), to address your 2nd point.

The view reset can now be triggered via a LoadFile() bool parameter.

I think it's best to avoid uneccessary feature bloat, however if something is especially helpful for development it may be worth adding it behind a build flag - so long as it doesn't get in the way of the main codebase and the added complexity is worth the extra convenience.
