* Initial support for using boxes for packing widgets. * Make CapiTalIzation more consistent * Move widgets to subdirectory * Removed nolonger needed resize function. * Small cleanup * When switching mode, reuse view, don't rebuild it. Reduces artifacts. * Needs cleaning up. * Remove separate prompt argument, use display_name * Simplify run-switcher code. * Add notion of parents, and trigger parent update on resize. * Use widget_get_height wrapper, avoid crash * Size separator width based on height. (indent) * TODO add margin to box. * First draft version of listview. * Add scrollbar to listview widget * Add padding option to box * Move access to global config out of widget. (1/2 done) * Remove printf * Make listview not access global config * Add click support, implement on mode buttons. * Re-introduce mouse handling on list-view. * TODO draggin on scrollbar. * Fix multi-select * Fix warnings * Fix include
