Good UI but some functions could be better

I enjoy using Airmail but some functionalities really should be improved:

. Search does not perform well (we can’t use combination of words for full text search for example) why not simply add support for Spotlight index? Many users are asking for this...
. The labels vs folders system is confusing does moving a message / conversation to a folder is the same than labelling it? When labelling a message, is the whole conversation labelled or only the last message? This should be simplified and/or explained.
. Conversations are not very well handled, it’s complicated to make operations on a single message which is part of a conversation and the other way around
. It’s too complicated to add a user to contacts or simply copy his/her email address.

Other than that, nice UI and ok performances without too many bugs
