I like the concept of this add-on but wonder is it still functional? I am using Kubuntu 12.04 and followed the steps for installing the helper add-on and then your add-on. I received a message that the service had been created but when I right-clicked in Dolphin or Konqueror to try it out, no entry was found in the Actions sub-menu.
Might it show up after a system reboot?

I was trying to do this by hand, as it is not so frequently i would use such script. I find it useful, but, hehe, dont need it myself. So, i found lots of tutorials and descriptions of how to make specific "Actions" entries, but wanted "Create new". This page made me think a bit (at last!) and I got it to work.

1. I made a folder (it didnt exist before) - /home/myusername/.kde/share/templates
2. I saved my template files - this time with Open Office writer and calc in this folder
3. the "Create new" menu had two new entries at same moment, without any restarts, but they didnt work
4. so i renamed them to "ODF text document.odt.desktop" and "ODF spreadsheet.ods.desktop" and now it works!

I'm sure this works with anything single file project. But I'm tempted to experiment further - what about making folders for some "manyfilesinoneproject". There are some video editing (like make new DVD) or 3D editing programs, which have lots of files for each job.

This is the service menu installer I meant to refer to above.

Another suggestion I thought of is have it auto add the ext. For example .png for png files. Enter the name of the template and go.

This is great. Thank you very much.
I do have a suggestion. Create some base templates to include with it. I'll try to create some for multimedia, scribus, OOo, and a few more over the next few weeks. If you'd like to help or want something specific (or anyone would just like to help to create a library of templates), you can find me at #arklinux, on freenode.net.

Thanks again!
