Problem : when I develop a macro, I often change the configuration in the "Template input" part of the "Macro Input" tool from "Text Input" to "File Input".
Doing that loses the previous data : moving from "Text Input" to "File Input" removes the data entered and moving from "File Input" to "Text Input" removes the pointer to the file.
Which is annoying.
Solution : keep the data or file pointer in the "Template Input" so that it doesn't disappear when changing configuration choice.
