Visual Studio Code (version 0.10.11 on Windows 10586.164):

Source code, documentation, signature, all look almost the same. The following issues make it difficult to read:
- Same background as the underlying text view
- Same font and color as source code for documentation and signature, even line heights matches
- Difficult to see where does documentations ends and where does the actual signature begins
- Signature is incorrectly syntax highlighted: only the const keyword is highlighted, while any or any other type is not
- Wraps the signature into multiple lines which makes it more difficult to read, even if I still have a bunch of space horizontally on my screen
- +1 Links in the documentation text look like highlighted keywords. First thought was it is a bug: even the text is colorized, then seen that they are links.

For reference, Visual Studio:

- Different background and typography, it does not feel like it is embedded into the editor (the other one looks like an area in the editor with a border, there is no depth)
- Documentation and signature is separated visually
- Signature colorized correctly (keywords, types, identifiers)
- Signature is not wrapped into multiple lines
Steps to Reproduce:
- Hover on anything
