After dicussion with Alex, we agreed that the commands implementation in Editor2 is not ideal. Currently, commands are global, which means all instances of Editor2 share the same command objects. As a result, for each command, it can not hold any properties which is specific to an Editor2 instance, if it wants to save such kind of information, it has to attach that it to the Editor2 itself, which is no good.

In addition to that, bug #1505 will be fixed along the way when I migrate commands to be per instance objects.

This modification will not be API compatible with previous version (0.4.0 Editor2) with regards to how external commands are handled (including registration and retrieval). This is against rules to be merged into a point release, so it can be argued that this should not be merged into 0.4.1. However, as the new Editor2 is just released with 0.4.0 (which happened one week ago), and 0.4.1 will be soon (in 2 weeks time), so I’d like to push it into trunk for it to be included in 0.4.1, but we’ll see what the consensus is.

I will probably document how to migrate Editor2 plugins from 0.4.0 format to the new one later in another post.
