Improve the ability to add reciprocal links in inter-topic and inter-map linking

While Mind Manager has good linking facilities there are still some key features missing, particularly relating to reciprocal/two-way and inter-map linking. These include:

1. Allowing the Reciprocal Link facility to create two-way links between topics in different maps. I have proposed this before (see https://community.mindmanager.com/topic/2062-allow-the-reciprocal-link-facility-to-create-two-way-links-between-topics-in-different-maps where this idea has received nine votes) but I would like to reiterate this proposal as part of a wider set of ideas.
2. Add an option to the Send Topic(s) to facility to include existing as well as new maps. The Send Topic(s) to feature is a great facility which can automatically create two-way links between source topics and their duplicates in a new map, but it can't be used with existing maps. This makes adding topics to an already duplicated map a frustrating process. Ideally this feature would allow the user to select a new or existing map to send selected topics to and in the case of the latter, nominate the topic in the existing map they should be attached to.
3. Add an option for reciprocal links when using the Map Roll-up facility. This is a very effective feature which can add all or part of another map (or the same map) to a map, with the rolled-up topic including a one-way link to the original topic. There should be an option to change this to a two-way link on both the original and the rolled-up topic.
