ContextViewer alternative

I'm currently trying to switch form Eclipse to IntelliJ. One of the features I really liked about Eclipse and couldn't find in IntelliJ is the Declaration window. I looked around a bit and found the ContextViewer plugin - which is very broken (doesn't jump to the correct line, and doesn't always update) and doesn't play nice with the dark theme.

Is there any alternative to this? Note that the quick definition window is also not what I'm looking for, since that one also doesn't update
