Perhaps, there are other ways of obtaining of the full tree of used templates?
I need a tree of templates, and also very much it would be desirable to see immediate all names of templates in the generated page.
Besides it I want not to correct in specific templates some code, and directly in a plug-in to make changes to an output. Hooks there are not present and врядли appear in the near future. If there will be a modification method immediately in an output, what probability to receive a problem at usage of this output in different plug-ins?
