I like the way SAP has put in some efforts to explain ABAP in Eclipse (AIE) IDE as a tool for ABAP development.
The feature explorer view helps as a good onboarding tool for developers to understand the new shortcut keys (or hotkeys if you want to call it)..

I have ABAP for Eclipse - HANA development installed. For clarity, I would like to provide the version installed.
ABAP has been my favourite programming language since 1998-99. It is simple and offers great debugging capabilities.
I'm sure, it is really a challenge for SAP to bring in similar features in AIE, but I'm sure it is a question of time.
I do like some of the featuers of AIE (ABAP in Eclipse) that has meant to be consistent or similar to using (se38/se37)
SAP GUI development.

the F3 to go back is just great, but there are of course lot of other features that I wish
the AIE has to bring in. To simply put this, there are many points it has brought in
to provide a seamless experience for the existing ABAP developers, which I beleive is
critical. Although I see the direction is headed towards that point.

The "Where-used" is one great feature I love it.

It does provide the inline code completion feature, which is again great.

I want to still check few things when we write inline enhancements (ENHO objects ). It (inline enhancements) is
bit tricky though here in AIE, but I need to spend more time there yet.
Having said, there is a lot of room for SAP to look at simplifying the tool further, providing the motivation for new
(and existing) developers to use more AIE for development.
Enjoy the AIE !!!
