OK now there is a website named xfce-look.org that is trusted by linux as github or git lab are and you can install theme parts to your system like in your systems add remove programs. Now it is for xfce though you'll see some stuff made for kde and gnome and cinnamon and they also have their own areas of the site like gnome look.org. Now if you want to do this the old fashioned way you can download and then open the files up in usr/share/icons or ~/.theme in the home area you can also in your distro's program installer add/remove programs type in , ocs-url, this allows you to install from the links to pages I will post further down. Now today I'll post some cool icon themes that impressed me with the skill and just quality of the icons and anyone can install them by just installing the ocs-url program. first up is a theme I adore since it's creator has some gift for art is an understatement, this is the buuf icon theme and there is another one for kde on the site also that is a bit different. https://www.xfce-look.org/p/1012512/ This is one that has all the icons on my panel which many themes totally fuck up like no file manager or terminal icon or more common no network connected or pulse audio icon. https://www.xfce-look.org/p/1291816 This one is surprisingly nice when applied on my desktop. https://www.xfce-look.org/p/1012539 Now you can install themes for xfce but remember the themes for desktop color schemes and the xfwm themes are in the same catagory so if you don't see the theme in appearance then check in the window manager to see if it's there. You can look on the page you open if it's tagged xfce xfwm which the xfwm is the window frame not the color scheme for the desktop but the window frame only. Now here is the basic xfce icon sets page sorted by rating since good ratings mean it installs right and is more likely to be a full theme without a bunch of missing shit. https://www.xfce-look.org/browse?cat=132&ord=rating Now you want a new mouse cursor or 2 or one with HiDPI capability for a 4k or a small hdmi screen then you can get one here also this is the cursors sorted by rating. https://www.xfce-look.org/browse?cat=107&ord=rating This is the color scheme and window manager themes, quite a variety to choose from though stunted by the xfce color pallette which for some reason seems to be set for 16 colors like windows 3.11. https://www.xfce-look.org/browse?cat=138&ord=rating
