-## Big change
+## Roadmap
 
-* Add tests for multiple moves
+See the sections below for details
 
-### More for moves
-
-* define macro to loop over moves e.g. #define FOREACHMOVE(action)
-
-### API goals:
-
-* manipulate move sequences (invert, unniss, cleanup, mirror / transform...)
-* solvers (optimal, generic, coordinates)
-* print cube (in various formats)
-* print ptables (or layout data in such a way that can be printed
-  easily, e.g. first bytes are null-terminated strig and can be
-  printed by user)
-
-### Solvers
-
-* Actually do A*, no fixed depth
-* Use threading (see below)
-* Return strings, newline separated (see nissy_ffi)
-* Instead of depth, I need the following parameters:
-  int minmoves
-  int maxmoves
-  a parameter for all solutions / nmax / optimal / -O n
-* How to make the above nicer? can it be done with a minimal
-  amount of parameters (e.g. at most 2)?
-
-### Rename to libnissy
-
-* prefix public functions with libnissy_ or something similar
-* move() that takes a string (alg) as input
+* Implement some simple solver
+* Extend cube and moves to include centers
+* More complex optimal solvers, pruning tables
+* Benchmarks
+* Multithreading (build-time option number of threads)
+* Other optimizations
+* NISS
+* Move manipulation utilities
+* Coordinate solvers and other steps
+* More output formats
+* Adapters for other languages (at least python)
+* More documentation (or keep all in cube.h?)
+* Rename to libnissy
+* Release 1.0
 
 ## Solving
 
-### Generic solver
+### Simple (slow, light) solver
 
+* Decide on API for solve() (see above)
+* solve generic becomes private, use cube_fast_t instead of cube_t
+* write simple solver based on generic
 * tests: solve full cube (max 7-8 moves?)
-* more tests: eo and other stuff
 * benchmarks

 Solvers
 
-The solutions are returned as a newline-separated list of characters.
+The solutions are returned as a newline-separated list of characters. Moves
+are separated by single spaces.
 
 Unless specified otherwise, all the solutions are not trivially simplifiable.
 This means that sequences like U U2 or R L R will not appear in any solution.
 Moreover, two consecutive parallel moves are always going to be sorted in
 increasing order. For example, L R2 may never appear in a solution, but R2 L
 could.
-
-Solvers return -1 in case of error, the number of solutions found otherwise.
-
-TODO NISS / INVERSE / LINEAR as a mask?
-
-All solvers take at least the following parameters, satisfying the conditions
-in square brackets:
-TODO more!
-        - cube_t cube [issolvable(cube)]: The cube to solve.
-        - uint8_t depth [depth <= 20]: The lenght of the solution.
-        - int maxsols: The maximum number of solutions to find. The solver
-          stops when the limit is reached. If set to a negative number, all
-          the solutions are found.
-        - move_t *ret: The array where the moves of the solutions are stored.
-          There is no separator between different solutions; to read the
-          solutions, use the fact that all solutions has the same length: the
-          i-th move of the j-th solution is ret[j*depth + i].
-
-Some solvers take other parameters. See below for details.
