Be warned! You should work on a copy of the lazarus.lpi project, else 
you'll get trouble whenever you want to rebuild lazarus later. In that 
new project specify an different output location for the executable.

You also may remove packages from the project, in order to speed up 
compilation and linking. I added a global Define to the compiler options 
(-dDoDi ;-), that allows to exclude parts of the Lazarus code, to change 
the caption of the IDE window (for better distinction between the 
debugging and debugged application) and more. As far as configuration 
files are read and written by the IDE, it may be necessary to make the 
Lazarus copy use different files, so that a rebuild of the working IDE 
will not be affected by experiments.

We should discuss this and further updates in detail - I stopped after I 
could not find out what options to set to which values.

My dream is a customizable Lazarus IDE project, where I can experiment 
with docking, SynEdit and other modifications. We also can meet in 
#lazarus-ide, to exchange our experiences.
