Add sorting order option “manually” to window buttons to be able to sort buttons also by drag&drop like before 4.8 !
Option to only show windows from current screen (for multihead systems).
Show workspace name in the tooltip when showing windows from multiple workspaces.
More flexible way of showing the button.
Rotate the buttons 90 degrees when the taskbar orientation is vertical.
Show buttons above each other when the taskbar is aligned horizontal and in a corner. Including grouping by task. Like BeOS does.
Allow fixed (constant) height of buttons when taskbar orientation is vertical and panel length is set to “full length”.
Option to control ordering of buttons, at least make buttons
well-ordered.
Options when a task should be visible in the taskbar.
Unhide the panel when a task becomes urgent in the taskbar.
Quickly close a task with (for example) a middle mouse click. Option for close Buttons on every Task? (most Laptop touchpads don’t have a middle button, and emulation dosn’t work well either) Implemented: right click, panel, panel preferences, items, window buttons, settings (cog icon), behaviour, middle click action, close window. I don't know how you missed it! ;)
Option to middle click / mousewheel shutdown or restart, i.e. add settings option in Action Buttons for which action to assign to middle click. Request for shutdown as default.
Option to enable hide/unhide or shade/unshade with the scroll wheel.
particularly with Logitech's freewheeling scroll, shade happens unintentionally A LOT!! ( - also happens when using a laptops scroll area on touchpad!)
Option to enable/disable icons in taskbar
Option to toggle dimming of inactive icons

When they esten grouped several applications, to have of general menu system to unhide, hide, etc. Very util with applications like Gimp.
Switching to the task on the left or on the right from the current one, and selecting first, second, …, tenth item in a taskbar (via keyboard - would need a new keyboard-event, like switching workspaces? Or maybe as a command, or a parameter to xftaskbar4 or sth?) (maybe also to up and to down if tasks span over more than one row)
Changing order of items in a taskbar by moving current task left or right (or up or down) in the list (again, new keyboard-event or a command?) (hmm… just released that a task order is a vague thing…)
Change icon size according to panel size. instead of a static 16×16 icon.
Add an option to display inactive and/or minimized windows as icon only, while showing the label only for active and/or normal/maximized windows. If it were possible, to make the Label apear instantly on hovering, it would be a nice expierience to watch them popping up and colapsing again, one by one, and you won’t have to wait for tooltip showing up to get the windows titleinfo - - Usefull for small screens and/or portrait view, especially on tablets & convertibles
Filtering: Show (only) windows from workspace [#] This would allow multiple panels/taskbars to correspond to the side of the screen they are on and another workspace is relative to, so you always know where your other windows are.
