 ### Todo
- - continue search with F3
  - TextInput text range selection (mouse and keyboard), handle longer texts
  - Scrollbar track click
  - view for multiple bytes combined as int, float, double, ...
 
 ### Changelog
+ - v1.5 - 2017-05-22
+   - F3 to repeat search (scrolls to next result till end of file is reached)
+   - welcome screen shader
+
  - v1.4 - 2017-05-16
    - added goto address panel (scrolls list to address) with format switch (hex/dec)
    - added search panel with format switch (hex/dec)
