It would be great to have a way, via API and TestComplete menu, to decide which ScriptExtension version of a specific ScriptExtensions or a set of ScriptExtensions should be loaded when TestComplete is in design mode.
In our case we do a have a set of keywords based on ScriptExtensions (JScript) and a set of keywords are supporting us to test the SUT.
This would give our tester the advantage to switch between different versions of some keywords.
