I'm sorry to make up this old post, but I'm very interested in the new 1.3 LT.
If I can tell You my personal opinion, I think LT will be better if the "plugins" don't need change in the templates.
This 'cause, for the Blog Sisytem with many templates... it's very hard to change every template in every update/upgrade of LT version!!
For examples, I use the "authimage" plugin.
This nees a little change of the code in only file.. buy multiplied for thirty templates.. it is a big work!!
But, why this of the most popular plugin, it is not included in the LT? (and rendered obligatory for the templates?)
I wanna close this my long post, with my best wishes for You.
LT is the best platform I found.
You are the best.
