Hi Timo,
In my daily work, I use mainly:
- an add-in that allows to do advanced searches in header files
- a "zip the project" add-in
- a converter for structures from MSDN C/C++ format to Masm syntax
But, having my own editor, I also have a tendency to add functions to the core editor, so I don't need many add-ins.
Why are you asking? Good intentions for 2017? ;-)
