 ## ExectOS Ideas
 This is a list of ideas that migh but not must be realized.

-### SDK
- - [ ] Currently XT Development Kit (XTDK) is a garbage. It should be cleaned up the way, it contains all structures
-       and definitions, as well as all routines that are exported and can be used by other components or software
-       dynamically linked. All other routines should be available as well in some form, as some libraries can share
-       code with others (eg. XTLDR calls routines exported by XTOSKRNL). This is partially done, as XTDK has been
-       cleaned up, but still there are routines used by XTLDR.
-
-### XTLDR
- - [ ] Rewrite memory mapping and paging support in bootloader to make it more flexible and architecture independent.
-       This should support paging levels, thus allowing to make a use of PML5 on modern AMD64 processors and increasing
-       the addressable virtual memory from 256TB to 128PB. This is partially done.
- - [ ] Implement editing boot menu entries directly from the boot menu. Changes should be runtime only (not stored on
-       disk).
-
 ### XTOSKRNL
 - [ ] Implement mechanism for detecting CPU features and checking hardware requirements. If CPU does not meet
       requirements, it should cause a kernel panic before any non-supported instruction is being used.
