Closes: #1526 Closes: #314 * debug log * semi-working prototype. works on the left and the center but not on the right * fixes formatting * fixes tests * - fixed tray_width_change signal - implements suggestions * - fixes error with tray positioning * - tries to fix tests. Does not work * - fixes tests * - implemented suggestions * reverted formatting in comake and doc * - changed unique_ptr to const reference * - fixed formatting errors in code * - actually fixed formatting(ran clang-format) * - implemented suggestions * - Added CHANGELOG.md entry(not sure about wording) * - removed bar_settings from tray_manager::setup * - fixed issue from rebase * - fixed issue with tests from rebase * implemented suggestions * Update CHANGELOG.md Co-authored-by: Patrick Ziegler <p.ziegler96@gmail.com>
