Are you considering to contribute the changes back?
For 1), I have already one pull request: https://github.com/rovo89/XposedInstaller/pull/13
. It needs a bit more work, but I will probably include this in a future version.
For 2): A log view is definitely planned and colors could be useful for that (even though the image is too small to see what it looks like).
The log export in 3) is useful as well, especially if you can copy it to the clipboard or send it to a text editor app.
I'm not sure about 4). The UI definitely looks nice, so I'm curious to see how it is coded. But is there any need for that? I guess no user would know what to configure there. So if you know any combinations of modules that require this, I would rather check if the framework can't figure out the correct order itself, or maybe give modules some additional control over this.
So as you can see, I would consider merging most of your additions, which would make sure everyone can enjoy them and that users can upgrade using the new downloader feature in version 2.2 (which would break with modified apps because of the different signature). If you publish your changes, that would save some work and time and it also continues the thought of Open Source.
Tired of updating your mod for every new ROM release?
You want give users the possibility to combine different mods without creating tons of different files for all possible combinations?
Then have a look at my Xposed framework
