Enhancement SDEVWORK (cmod) / Hide Sourcecode

Hi folks,

are there any BAdIs or User-Exits for the new ABAP-Editor called everytime

prior sourcecode is loaded/displayed (SE37/SE38/SE80)?

There has been the Enhancement (CMOD)

SDEVWORK: Development Workbench customer exits

which doesn't seem to work any longer due to the new ABAP-Editor?

I want to avoid that anyone can view certain sourcecode. Any ideas?

Tnx!
