hi, just to say that i noticed this the other day too (not a big problem for me but you actually gave me an idea :)

the Research Tree, only needs to load one time, and then when you make a new game, it loads it up instantly as though it remembers it...

so if there is a way to make it on a per-save basis, (addressing your issue too), like with ogre stack settings and other mods, then maybe there is also a way to refer to it whenever a game is loaded up again, without it needing to re-generate the whole tree_creation process?

in theory = if we dont add new mods to an existing save game, research tree loads up in seconds :)

If it really does, this should be in description. I was avoiding this mod thinking that researchpal is better in analysing 300 mods research but this feature makes research tree much better.
also researchpal has same issue but it loads every time I load game

ah just to clarify... as far as i remember, research tree and pal, always need to fully generate the tree, per launch of the program... (pal does it on startup, as opposed to onclick,)

it's just that ive noticed that if i play a save game, and then go to the main menu, and start a new game (or vice versa) the research button loads instantly the 2nd time around, as it keeps it in memory. thats what gave me the idea above :)

actually i had posted on the pal thread why i switched over to research tree, just in case you fancy a long read :)
