Hi Albert,
thanks for trying out laslook.
In past LAStools was a windows tool. So most of our customers are windows users. Last year we started to port the non-open-source part of LAStools to linux due customer requests. Those users wanted to use LAStools in a cloud/server infrastructure without GUI. So right now we have not much request to du GUI on other systems than windows.
Anyway: We like linux and macOS - so may we start a port to those systems also for the GUI. But for sure this will take some time.
Some improvements on the windows version will be first to make the software even better.
Best regards,
Jochen @rapidlasso
