...having hfs the whole time monitoring if there was a change in the template. Or is it supposed that we edit templates every day several times?
HFS wont monitor changes with this current idea, but rather READ the external .tpl file. So any changes are instant. It will allow for more dynamic usage and editing of the .tpl file.
I really like this idea of reading an external file instead of reading the internal template. The current template editor could just read and show the current selected .tpl file. This method screeams advantages, it could even fix the character limit bug on older machines/OS's. Comrade Elisey had a bug where he couldn't import the entire template, if it was over a certain size. But other external programs had no problem like this. So he could now use external programs to edit these template files.
Also we can make template installers for our templates, which will be really cool for novice users.
And yes, some days i edit the template quite a lot, template creation is quite a painstaking process sometimes.
