I'm working a lot with framework specific java libraries which contain some custom extension file like .palette or .lexicon. This files are mostly XML or simple Text Files.

JD-Gui won't open them because the extenstion isn't associated with known extension like .txt or .xml

Searching in this repo I found #28.
I followed the steps and created TextFileTreeNodeFactoryProvider.properties in my jd-gui installation folder but after restarting jd-gui the mentioned file won't open.

I'm working on win10 with JD-GUI Version 1.6.6.

Is it possible to make custom extentions configurable from a config file ?
