Is there any form of external tool integration, or API that supports building one (think something like a Eclipse plugin) ?
The editor for non-transaction based work (such as HTML, XSLT, etc.) should be considered unacceptable by all serious developers. Crashes, memory-leaks, lack of syntax-highlighting, etc.
While I'm aware that I can obviously code in another editor, and then copy&paste the code over every time I want to test something, this is a approach that's not only stupid and time-consuming, it's also very error phrone, and often causing loss of data.
A integration to Eclipse, either by a specialized API, or version-control integration with NDWI (if that even works, seems that nobody use it?), would make development much much less painful, and more efficient.
Even if this is completely impossible now, let this be a suggestion to the developers for much needed improvements, if this tool is to be taken serious by modern day developers. External version-control support is also a really big lack in the product. A home-made centralized VCS is hillariously inefficient. If the system had been build on standard-solutions such as SVN, atleast a Mercurial bridge could been done.
