Dear Slickedit,
Being an ardent user of slickedit (ofcourse still on 10.0) as its expensive to buy in growth markets. Each year I evaluate the updated trial version and park it upgrade for the future.
The feature I am look at is
- support for the newly emerging Dynamic scripting languages. I see scala,Go isn't supported yet. It would be nice to add it.
- Gearing up for the cloud era, PaaS providers have unique way of creating projects using command line. Ability to create projects with PaaS providers, and intergration of code to GitHub.
- Ruby on rails is very popular and has lot of traction in community. As a developer I need ability create a ruby on rails project.
- I am not sure if maven support is provided for Java in the current version. I have seen Ant in slickedit 10.0. If not that would a good one.
- Import and export from other popular IDE's like eclipse, netbeans (This isn't a high priority thing though), as you can always create a new project.
- Finally a humble request making it cheaper in growth markets (I live in india).

Some of the features are going into the IDE world, but those are my thoughts.
