Widget Templates backup by thunder

I just added a field to one of my modules and got asked the question if I want to update the module.

Knowing that it would recreate the basic template I clicked yes. Never thought about that it would also reset my copied custom widget :-(

Fortunalely this was no big deal I could recode it in 5 min.

However since working with thunder I don't think I have a local copie of that

a) I would like the updating only to update the widget templates that Sitefinity created
b) if this is not possible some sort of backup system. Imagine you worked 3 hours on a template and someone else adds a field and messes up your design. You notice one day later after 30 pages have been change. 

What then?

Hello Markus,

Thank you for contacting Sitefinity support.

I am sorry to hear that you have had trouble with Sitefinity.

a) Updating all widgets, including custom, is implemented by design in Sitefinity.
b) I have reported backing up templates as feature request to Thunder team, who would discuss it's implementation and decide if it is possible.

In case you have any other concerns I would be glad to assist you. Thank you in advance.

Regards,
