Question about technology, flashlight and manipulators.

Hello. I would like to clarify a few questions. I sort of finished the game in its current state (only the last task for the Victor terminal remained). I opened all the doors, scanned all the tablets with improvement files (I specially found on the Internet a map of the entire game indicating where they are), but still there are not open technologies in the improvement tree. These are the technologies I cannot unlock: 1. MOLE F 77 (Flatten) and everything above it. 2. M-TrackReach 3. 3. MDR Power Trim 2 and everything above it. 4. CoolDense 2 and everything above it. I don’t completely understand what needs to be done to unlock technologies. I can't find any information in the game. What do I need to do? Second question, please do something with the main character’s flashlight. It is so low-powered that it is practically useless in dark places (and there are plenty of dark places in the game, depending on the specifics of the game). The third question is, do the developers have plans to add 90-degree rotatable manipulators? And lastly, do the developers have a plan to add something like a resource destroyer to the game (otherwise some resources accumulate and have nowhere to go).
