Implementation-wise could make sense for the implementation be in the panel itself, tough it may be difficult to control from the external panel configuration tool Usability-wise i think would be fine if the first spacer is added at the end of the panel, and the second at the beginning, trigering the centering for the whole panel contents, tough again is a bit difficult to trigger from the external panel configuration toolbar REPOSITORY R120 Plasma Workspace REVISION DETAIL https://phabricator.kde.org/D27481 To: mart, #plasma, #vdg Cc: plasma-devel, Orage, LeGast00n, The-Feren-OS-Dev, cblack, jraleigh, zachus, fbampaloukas, GB_2, ragreen, ZrenBot, ngraham, alexeymin, himcesjf, lesliezhai, ali-mohamed, jensreuterberg, abetts, sebas, apol, ahiemstra, mart
