Mostly Harmless

This is my very first selfmade Sudoku, I hope you like it. Feedback is very much appreciated.
Rules:
Standard Sudoku rules apply: Every row, column, and 3x3-box contains the digits 1-9 exactly once.
Digits do not repeat within a cage and sum to the value indicated in the top left corner.
Numbers outside the grid with an arrow next to them state the sum of the digits along the diagonal the arrow points at. Digits may repeat on this diagonal if allowed by other rules.
Numbers outside the grid without an arrow state the sum of the first N cells in that row or column, where N is the digit in the first cell in the row or column (both counted from the end the number is placed at).
Cells with a black dot between them contain digits one of which is twice the other. Cells with a white dot between them contain consecutive digits. Cells with an X between them sum to 10. Not all these symbols are necessarily given.
Solution code: The digits on the diagonal to which the clue outside the grid refers, read in the direction of the arrow (7 digits without any other symbols)
