Hey Andreas,

cool stuff! See inline comments below for more feedback.

I think it's pretty fine already. What I'd change are the screenshots of 
Massif Visualizer and Heaptrack. Both should use the bright breeze color 
scheme, and for heaptrack best show the flamegraph tab of heaptrack_gui. I'll 
send you two screenshots in a minute.

Now, some rewording from my side:

KDevelop:
helps you get the job done while *staying* out of your way

Massif Visualizer
– profile your heap with Massif from the Valgrind suite
– then use the Visualizer to spot leaks or find places in your code to reduce 
your memory consumption

KCacheGrind
– profile your applicaiton with Callgrind from the Valgrind suite
– visualize the call tree of your program, find where time is spent
– analyze how your program utilizes the CPU caches

Heaptrack
– a heap profiler like Massif, but much faster
– collects more data so you can find temporary allocations, measure memory 
throughput and count the number of allocations
– supports runtime attaching

Btw, I second what Aleix said regarding the ".-" and the KDE logo.
