Thanks, today I delved into some tests, I noticed that on the Scalos Workbench there is no menu, Wander/Scalos for the various functions on Icons and Files and there is no possibility of the automatic arrangement of icons even in the prefs (maybe I don't find them) also on some icons the text is not visible, to make it visible you have to move the icon.
From the Scalos Preferences I enabled the Buttons and Tabs and they work fine , only flaw the background of the two Tabs too big and dark gray "not editable".
At the end with the transparencies I managed to improve the aesthetics of the two Tabs (see screenshot), they work well but when you change from Icons to Detail, Name, Size, Date etc... in the Window there remain shadows of the icons (graphical artifacts), and some icons (DualPNG) are cut off, see screenshot
