 	- use posixes pthread_rwlock_init(3POSIX) mutexes to allow reading to arrays and other types
 	- do not have the illusion that you can append to an array of pointers without non-shared locking, because you realloc that array of pointers, appending must also be non-shared locked
 	- _free functions shall never fail - do not use timed locks
-	TODO: make it work.
 	- i changed arrays from type arrays to type pointer arrays, so code that allocates must be reimplemented, also struct free functions and -> instead of . in array elements
-	- make mutex locks in api and ui thread
-	- make the ui thread
