What is the best way to see this change reflected when viewing it in TM?
For messing with TM files, find one that works and make a copy!
Edit the copy to try out any changes. Ensure copy is in the folder with other TM files.
Use MB view Theatre Mode [name of your TM file here].xml option to see changes.
That works fine the first time you do it. ie make a default2.xml file and use it in TM (I have to add it first via [View / Theater Mode / Add Skin] for it to show in the list - is there a way for it to automatically show up after it's been added to the same folder as all the other ones?)
Anyway - you look at it and think 'grrrgh - need to increase that x value' so you modify the default2.xml source file.
Close TM down. Open it again with the same file and the change is not reflected.
How do you do a 'refresh' here? It's like it caches it in someway - it doesn't re-read the file.
