Issue I450 [80,gui,enhancement,resolved] Lua expressions supported in text box controls. As of 8.0.4-TEST18, Lua expressions can now be used in most text box controls. Just type '=' followed by the expression. For example, with the "quad" example open in View, click on the Variables tab, and in the _percent_tune variable field type =20*4 which results in 80. Implemented in 8.0.4-TEST18.
