Hi Scorpio

first of all a huge thanks for your great SW, I used it to quickly create draft of a schematic instead of doing redlines for the drafter in pdf or powerpoint ;-)

I just hit a couple of issues with the dev version (QElectroTech V 0.90-DEV+1eed13c61b0a58100c957a06d79751d3)

1. when creating new parts in the library, not all folders show the prefix correctly, even all are added in the same way to qet_labels.xml
actually the first 3 categories work with all the sub categories, the further ones not at all...

2. I defined wire numbers in a slightly weird way, as "sheet number + 2 digit counter" now first of all the counter counts over the project, not over the sheet, but thats a minor thing, but worse if I connect wires via off sheet connectors, on reopening the project the wire numbers get mangled, i.e. a wire 0201 gets to 0801 on sheet 8 etc. this also if I set the project to production ready.

3. the TB generator plugin works fine on the industrial.qet example, but on my own project it fails with the following message:

if you have time to have a look, please let me know if you need more info, will happily share more details with you.

Thanks and regards
