I’ve been busy tweaking some of the more basic functions within the Toolbox GUI this morning.
A quick bit of code to check that a template does actually exist within the file opened has prevented an error message appearing when you try to change it … within a template file.
Also on the basic functionality is an extra label running along the bottom of the Toolbox GUI which shows if the current file is Read/Write (with a red background) or Read-Only (green background).
