GuiXT Script Editor
The new GuiXT script editor is especially useful for developing InputScripts. It supports syntax-coloring, integrated help (F1) for GuiXT keywords,  easy navigation to "include" files or "process=" files, pretty print (indents if/else/endif), putting code blocks in comment, inserting  commands, writing backup files. When you work with large scripts, it will considerably facilitate your work.

InputScript Debugger
In addition to the InputScript trace function and the "visible" processing, the debugger allows you to process the script line by line, to set breakpoints, to display variables and to evaluate expressions.

Support for special controls
Complementing the general approach via SAP GUI Scripting ("applyguiscript"), some control functions can now be performed directly in the InputScript. The Input Recorder generates the right command for you:
Enter control="..."  item="..."  event="..."
This works in ITS environment as well, in contrast to SAP GUI scripting, which is restricted to SAP GUI for Windows.
The handling of certain events (user clicks on a control button or a menu item) is also supported:
On control="..."  item="..."  event="..."
