Custom View column drag rewritten with pointer events (replacing native drag-and-drop): grab a column by its grip or anywhere on its header (a click still sorts); the real column slides into the slot it would land in as a translucent striped ghost while a label follows the pointer. Only the horizontal position decides the slot. Esc cancels; data refreshes wait until the drop; wide tables scroll near the edges. Filters: - List columns (software, tags): "Has any ticked" / "Has only ticked" toggle - e.g. devices missing only Adobe Acrobat Pro - Space columns: filter by disk size (221 GB, 442 GB, no reading) plus a free-space rule (any / at least N GB / less than N GB, default 20); sort by disk size or by free space (numeric, no reading last); header clicks cancel these sorts - Menu controls no longer shrink when the menu is height-limited

/*
|
|
* Layout helpers (see layout.css).
|
|
*
|
|
* Sticky headers: measures the top nav and each table's group header so the column
|
|
* header rows can stick directly beneath them (--nav-h, --sticky-top, --thead-r1).
|
|
*
|
|
* Card view: on phones and tablets each table row is shown as a card, with every cell
|
|
* rendered as "Column name: value". CSS can't look up a cell's column header, so this
|
|
* copies each header's text onto its cells as data-label.
|
|
*
|
|
* The dashboard re-renders its tables constantly, so both are reapplied (once per frame
|
|
* at most) whenever the DOM changes.
