The Basic IDE has a nice toggle button in the standard toolbar to hide/show the Object Catalog, which frees up horizontal space for programming. We should also have a toggle button to hide/show the Watch and Stack windows, to allow users to free up vertical space as well. Currently this is kinda possible using the slider, but having the toggle button could provide better UX. This has already been asked for in AskLibO: https://ask.libreoffice.org/t/calc-ide-close-watch-window/60826
