There is no timeline, as it's very hard to predict not only how long some feature will take, but how much time I'll have for it. There is a "sort of plan" on the Features Requests page.
Dictionary is one of the top priorities, I plan to put the existing "grepping" solutions into the next release. It's all quite... opportunistic. When I see a possibility to implement a feature with little effort, I do it.
From my personal viewpoint, mm, I'll add Georgian language support. Which, basically, comes down to choosing nice font and copy&pasting ttf glyphs 3 times...
