The tool should be updated for Beta 15 now. I did not check every description, so some of them might be outdated. I added one new perk ("Tandem Warheads") and updated the perk "Psi Shadow", which is now called "Concealment" and is no longer a Psi ability. However, I kept it with the Psi abilities and did not move Tandem Warheads to an appropriate spot (I added it at the end) to avoid incompatibilities. I will clean things like this up in case one of the future betas includes big changes or once the mod leaves beta. For the time being, this would create more problems than it would solve. Note that Tandem Warheads does not work with versions before Beta 15. I also added a new tool - a base planner: http://xcomperktreeeditor.coffeecup.com/Base_Planner.html It should be pretty self-explanatory and works similar to the Editor. You can plan your base and the tool shows you the power state, your research boost, your workshop rebate and how many satellites the base can support. Since I do not know of a way to let the tool calculate this automatically, you have to tell it how many satellite/power etc. buildings are connected, otherwise it will show you the wrong result. Please let me know if you encounter any problems or know of changes to the mod that I am not aware of. Edit March 11: Added a tool to modify the stat upgrades that are not related to the perks: http://xcomperktreeeditor.coffeecup.com/Stat_Upgrades.html
