Collapsable module GUIs

[rafalcieslak]

Some modules may take up a lot of space, especially if they have a large (32+) number of sliders (e.g. a harmonizer with many voices). On one hand, the user must be able to access all these params, but on the other it clutters up the workspace.

The proposed solution is to make most models collapsable. A button on the module GUI would toggle the GUI display between two (three?) states:

1. Full module GUI displayed, all sliders are visibile, module GUI requires a lot of space.
2. Partial module GUI display, only the most important sliders (e.g. base frequency) are displayed, the rest is completely hidden (though connections still work, they might be displayed as if they ended on the collapsed slider), the space required is significantly compressed.

Optionally, a third mode might be useful:

1. The GUI is completely compressed, no sliders are displayed, only the name and iolets are visible, thus the module takes absolutely minimum space.
