We pay attention to any performance related problem found by our users and try to fix them as soon as possible. If you ever face this experience again I strongly recommend you to report it immediately so we can reproduce it and provide a fix for you.
The Gradle support is a part of Community Edition. Code completion should be available for dependencies and plugins (available in the Maven central). I've seen a few cases when there were no completion for the artifacts from the local Android repository. It will be fixed shortly.
as it was commented below IntelliJ IDEA includes almost the same support (mostly the same) for other languages (PHP/Ruby/Python) as other IntelliJ-based IDEs. But at the same time IntelliJ IDEA never was positioned as a "true" polyglot IDE. IntelliJ IDEA is Java platform IDE, in the first place. It does support other technologies via plugins though, it might be much more convenient to use dedicated IDEs for other technologies.
we know about this request and understand it's importance. however it can't be done quickly as there are some things to change in the core of the editor. i hope to see it in 14 or even early nobody can tell in advance. will keep posted. i'm sure it will be implemented
Please contact [email protected]. If you buy IntelliJ IDEA I hope sales can help you with getting WebStorm for free (or with a discount). Scala support is part of IntelliJ IDEA Community Edition (which is free), but IntelliJ IDEA Ultimate has additional nice features.
the python plugin for intellij adds similar level of code assistance (including django support) as pycharm. the only difference is in releases dates. intellij idea gets all new features with a small delay (and vice versa pycharm gets some new features with a small delay after intellij release).
