Great! Out of the 12 plugins I've adapted so far, only 3 actually needed 
a change in the source code, so you might be lucky.

Mostly it was related to missed layer change events when the layer was 
already present at time of installation.

For example in the photo_adjust plugin, you couldn't move the photos 
with the mouse when the photo layer was already active at installation 
time. You should also check that the disabling and enabling of buttons 
and menu entries works as expected.

What I did was read the source code of the constructor and 
mapFrameInitialized method of the plugin main class and look for 
something that might not work when a MapFrame already exists and layers 
are open.
