@@ -7,7 +7,6 @@ todo (small tasks):
 - review C errors (raise segfault, backtrace?), use callback and jit flush.
 - review slices indexes (and positions) for backtracking (+ entry & exit).
 - review vector specialization in mtable, replace by table and col mth tovector?
-- replace reshapeto_ by append_ to vector/matrix in mtable.
 - improve MADX converter to handle mult. line def. and mult. def. per line.
 - improve speed of mtables (still need proxy lambda specialization for speed).
 - redo map diagonal blocks from beta0 block in bet2map (unique solution exists?).

 - improve speed of maps (alloc+intrf 70%, method 4 vs 2, chrom vs HO, skip t).
 - improve speed of objects (copy on creation, fast copy?).
 - module for managing particle vs damap and their attributes

 done:
+- read damap
+- ptcorder option when writting gtpsa
+- add pb dir to gtpsa convert to (re)move canonical variables.
+- beam beam 4D.
+- dispersion in 6D
 - fixed synch_1 to synch_8 for backtracking.
 - fixed synch_1 and 5, added synch_6 and 8.
 - clear attempt for cachemethod and objalt.
+- replace reshapeto_ by append_ to vector/matrix in mtable.
 - detect the need for cofind in twiss and remove the attribute.
 - update beta0 to ease its creation from vector of coordinates.
 - update cofind and twiss to use nocopy, par2vec and vec2par.
