- test what windows can handle (the number of partitions)
- better keyboard focus handling
- end sector in Create
- add warnings for scsi drives if you create more than sdx15
- the information put in save/restore partitions must be cleaned
(remove mounted/formatted/..., also remove the Data::Dumper dependency)
- test, test, test
- do not allow swap partitions above 2Gigs
- wanting the first partition to be extended is not used
- maybe warn if a mounted partition change of dev number
- text version
- better error handling (what to do if we find a bad partition table?)
- display the information about the correspondance color2type
- handle the partition labels (missing information here)
- add comments in the code
- add documentation
- handle the `luke' case (main extended partition must be extended)
- ability to batch actions (like chained moves)
- add a verification after fdiskReadPartitionTable that the start_cyl,
end_cyl... do correspond to start and start+size. For the moment, this
information is just discarded :(
This verif can't be done in fdiskReadPartitionTable as start is relative in
extended partitions
