It seem's the time to update roadmap now.

I suggest a bit later, after we will have some users feedbacks, create release with improvements (bugs, translations).
Then release with some light features like:
- simple calculator in New/Edit Transaction Dialog.
- Transaction filtering – Allow the user to quickly find and edit transactions.
- Budgets conform to a financial year defined by the user.
- Budgeting:Subcategories

And we should discuss future of investments dialog functionality. How to sale, transfer money from or to investment accounts, dividends, etc.
