History
Creating GUI applications on Amiga was difficult for a very long time, mainly because the programmer got only a minuscule amount of support from the operating system. Beginning with Kickstart 2.0, the gadtools.library was a step in the right direction, however, even using this library to generate complex and flexible interfaces remained difficult and still required a great deal of patience.
The largest problem in existing tools for the creation of user interfaces was the inflexible output. Most of the programs were still using built-in fonts and window sizes, thus making the use of new high resolution graphics hardware adapters nearly unbearable. Even the preference programs on the Workbench were still only using the default fixed width font.
In 1992 Stefan Stuntz started developing new object oriented GUI toolkit for Amiga. Main goals for new GUI toolkit were:
- Font sensitivity Possible for the font to be set in every application.
- Changeable window sizes Windows have a sizing gadget which allows users to change the window size until it suits their needs
- Flexibility Elements can be changed by the user regarding their own personal tastes.
- Controlling by keyboard Widgets can be controlled by the keyboard as well as by the mouse.
- System integration Every program has a REXX port and can be iconified or uniconified by pushing a gadget or by using the Commodities exchange program.
- Adjusting to its environment Every application can be made to open on any screen and adapts itself to its environment.
MUI was released as shareware. Starting from MUI 4.0 it is distributed for free but shareware key is still required to activate all user configuration options in MUI 3.

Famous quotes containing the word history:
“History is the present. That’s why every generation writes it anew. But what most people think of as history is its end product, myth.”
—E.L. (Edgar Lawrence)
“Social history might be defined negatively as the history of a people with the politics left out.”
—G.M. (George Macaulay)
“the future is simply nothing at all. Nothing has happened to the present by becoming past except that fresh slices of existence have been added to the total history of the world. The past is thus as real as the present.”
—Charlie Dunbar Broad (1887–1971)
