I have received some requests about allowing to save and load net tracer configuration, since it's tedious to enter every time.
Basically, there is a concept of "technology setups" already but it's not active yet. For a short-term solution, I have prepared a script which adds a "Technology" menu with two entries: Save and Remove. "Save" will ask for a technology name and save certain settings (grids, layer default table, net tracer setup) under the name. A new menu item will appear in the "Technologies" menu with the technology name with which the settings can be restore.
Multiple settings can be saved (they are persisted in $HOME/.klayout_tech_info.txt) and selected with the menu item.
"Remove" allows to remove a setting.
The script is available for download here: tech_manager.rbm.
The script is rather a blueprint for similar scripts: it can be changed to allow to easily switch between different display settings and similar. Please note, that this is just a temporary solution. Later, there will be some technology info management within core KLayout.
I hope that it useful,
