Trees seem to grow at differing rates so I've taken to sampling trees to check their maturity. It would be great if we could mark which trees are suitable for felling. This would allow us to run through a plantation quickly marking trees then once the majority are ready, we could bring in the trucks, or outsource the work, as is done IRL. "Go fell all the marked trees in that forest".
The easiest way would be to add a right-click function to the Soil Sampler that paints a high-contrast band around the trunk around chest height. A more immersive way would be to remove tree sampling from the soil sampler, and add a new tool "Forestry tools" which incorporates tree sampling and a couple of cans of spray paint. Again, left-click to sample, right click to add or remove a mark.
Thanks for your consideration.
