Display Multiple Layers with Transparency

As a user, I would like to be able to view multiple map layers at the same time and adjust their transparency individually so that I can directly compare maps, sketches, aerial photos, or drone footage with one another.

This is particularly important when inspecting solar power systems, rooftops, or other large-scale structures, as it allows for a direct comparison of the actual conditions with the plans. A semi-transparent overlay of different layers—such as a CAD plan and a drone image—would make deviations, damage, or construction errors visible much more quickly and simplify documentation.

In addition, a freely usable drawing layer would be helpful for adding markings, sketches, or comments directly to the plan without altering the original plan. This would allow observations, measurement points, or defects to be clearly documented during the inspection and subsequently communicated in a traceable manner in the report.
