 * Use [modern path pattern](https://doc.rust-lang.org/edition-guide/rust-2018/path-changes.html#no-more-modrs)
 * One module implements one GTK widget, it may include additional helper files in same location (like template, CSS or DB API)
 * For children widget - create children module, located according to hierarchy
-* The codebase of module must be as minimal as possible, separate to sub-modules:

+#### Codebase
+
+* The codebase must be as minimal as possible, separate:
   * different tasks
   * massive structures
   * structures with implementation
 * Every module must:
-  * encapsulate: compose childs and stay composable for parents
+  * encapsulate it members: compose childs and stay composable for parents
-  * access 1 level of child API, never parents (e.g. through `super`)
+  * access 1 level of childs, never parents (e.g. through `super`)
   * implement only one `struct` (same as one file for one class)
     * implementable `struct` is public, where members - private
   * contain main `struct` implementation:
