I am missing the many features of MR Tech Toolkit Ohodnoceno 3 z 5 hvězdiček

Since MR Tech Toolkit is not compatible with Firefox 4 I had to change to Nightly Tester Tools and Compatibility Reporter. But I am heavily missing the many more features that MR Tech Toolkit had.
Can you, please, add them to your add-on?
That would be great.
