New Theme

[rockinaway]

When I install a new theme, how can I apply all the template modifications made by MODs to the new theme? Or do I have to install all my MODs again?

Or do I have to install all my MODs again? -- yes

Modifications only need to be reinstalled if they made changes to templates in their install code.

You could try to set your new style as a child style of a style in which the templates are already changed, otherwise you will need to redo the changes in your new style.

It seems to be working as a Child Style :D
