Not really a bug report but something that can be fixed on the next edition of LRTimelapse – some people probably don't mind it though.

Whenever I open LRTimelapse, it pops up with the introduction window/box thingy, however I cannot swap to another app to make it disappear until LRT has loaded?

Can you please make it so we can switch between apps (we all multi task ) while LRT is loading?

I assume you are talking about the splash screen? And I assume you are working on a mac?
You are right, on mac the splash screen comes to front again, after you bring another application to front. Currently I don't know how to change that, but I will have a look. On Windows this does not happen. Normally LRTimelapse starts pretty fast, so I've never noticed this before you mentioned it.
