how to approach custom settings/climas

[Demostenes]

During my work with l3dt, I ve modified lots of default settings, created new climas, etc...Problem starts, when I need to upgrade to higher version (I have no clue what I modified after some time), or when I need to open project on other computer with fresh install of l3dt (lots of files missing, etc...). So how to approach this problem?

Logically all settings should be part of project, would saving all new xml files into project help? It is really possible to save everything to project, to be not dependent on l3dt installation directory? Anybody have experience with this? Thanks.
