diesieben07 you have right that this particular example is more suited for NEI. (But now please go and update CameraCraft to 1.5.x and 1.6.x, because without those updates i cannot treat you seriously, sorry).
Development is a process to make things better. More functions and making them more efficient. I don't want to force any one solution, but i want to think of new ways, new ideas and path for the future. Don't see me as enemy, but as resource of ideas. I don't know every technical aspects of Forge, or any other mod, but my ideas still might be useful for someone. I'm not programmer, but i still want to be useful.
Besides, forge have "dormant chunk cache" and someone could say that this not fits to the idea that "if you install forge and no mods you should feel like it was pure vanilla", but something like Optifine. So please don't tell me there is a MIGHTY LAW that force only one strict direction of actions. I post the ideas, and developer chooses ones they like, and thats all.
About dormant chunks cache i wonder if it be useful for game trace of frequently used chunks and give them higher priority for keeping them in cache. Maybe even loading them first from list of needed chunks.
In field of loading chunks i see a great amount of things that can be upgraded. Square map is simple, but surely not effective. If we take distance of view for consideration, then circle would be optimal, because corners of map are less useful for player than middle area. Maybe some compromise between square and circle.
When traveling chunks should have more priorities than "in front of player" and "not if front of". Direction of moving and distance from player should have even greater impact than that. Often there is situation that game is loading chunk we are currently leaving before that we are currently entering. This is especially problem on slow network connections. So speed of movement should be taken for consideration to request chunk from server in advance.
