LiClipse 1.1.1 has just been released.
The major change in this release is that the minimap is enabled by default (for PyDev and LiClipse editors). With this change, the scrollbars are now also hidden by default. It's still possible to revert to the old style in the minimap preferences (but for me the current style is much better -- especially when using dark themes).
Below is a snapshot showing a 2.000 lines file in the editor... unfortunately I wasn't able to remove the scrollbars in the tree (believe me, I've tried), but without the scrollbars in the editor, it's already much nicer!
Besides that, StringTemplate and YAML are now also supported.
And at last, it's possible to debug Django Templates by adding breakpoints (in the LiClipse HTML or Django Templates editors).
