Minor point, the VibrantInk 'red' is too dark or low contrast to the background, at least for me. Thank you for adding Themes, especially dark(s).The new IDE will allow changing two types of themes: the IDE itself and the code editor.
The code editor themes use the same format used by Visual Studio. This makes it quite easy to "import" Visual Studio themes to B4X: http://studiostyl.es/
Adding new code editor themes is a matter of placing the xml file in the themes folder.
