Unfortunately the "map" of the network didn't come through on those screen shots, but the previous links took me to where I expected you to be and I would guess the lack of the map image is something related to github and screen capture. Regardless, yes the thought was to offer a sort of way to see the upcoming direction(s) of the plugin. Each dot on the line represents a saved change. There is a description that displays when hovering over the dot. Clicking on the dot opens a new window and takes you to the specific commit (change) that was made where you can see both the description, any comments, and the specific code changes to support that change.
Previously I believe you had been able to find that specific change because I had created a separate branch the name of which clearly described the intended change. That branch had multiple commits in it (more than one file was modified and modifications were done online instead of from a computer where more control can be had on how the changes get saved). All of those changes were summarized into the one commit to which I directed you. It can be found in the "dots" before the end of master.
Another reason to send to the network is because there are multiple little branches that I ended up stacking into a single chain. I expect that I will be able to confirm each chain off of the master one by one and then merge that change directly into the master branch. Thus, if you were to go to the last branch, you would see how the software is expected to be configured to reflect as if all changes were incorporated. I have thought of a few changes made that I want to let up on to support how others have likely built off of EP4 and not require them to make changes in support of some upcoming export features. Plus I haven't completed the matching import changes to some of that, so they may get bumped a little. Doesn't do a lot of good if can't import what has been exported. :)
So ignore or not, can do either. I know there was a date related issue that you had identified and I at least attempted to correct, though I'm still testing import aspects (having to be sure I have a backup/restore path for the database before doing that).
Sorry for removing that branch, but like I said was getting too "busy" for my tastes and management of ensuring nothing was left off/out.
