ILSpy showed the current location only implicitly in the tree selection and kept search in a separate docked pane. The omnibar, modelled on the Files community app and jiripolasek's EditorBar, puts an address-bar atop each decompiler document: a breadcrumb of the node (Assembly > Namespace > Type > Member) whose segments navigate and whose chevrons list child nodes, turning into a search box on typing that reuses the existing search engine. It coexists with the docked search pane and ships off by default behind the Options / Display 'Tab options' EnableOmnibar toggle, which applies live.

The Avalonia port had placed the UI app in an ILSpy.* namespace tree,
while the csproj RootNamespace and every prior release (through 10.1)
use ICSharpCode.ILSpy.*. Restoring the historical namespace reduces the
public API diff against release/10.1 for plugin authors and removes the
shadowing that forced global:: qualifiers in the test project. The
Images class and AccessOverlayIcon enum move back into the root
namespace (as in 10.1), since an ICSharpCode.ILSpy.Images namespace
would shadow the Images class for all code inside ICSharpCode.ILSpy.

Two failure modes that both showed the user the "no" cursor with no
other feedback:
1. ResolveDropTarget returned null when e.Source had no
SharpTreeViewItem ancestor, so Explorer drops landing in the gap
beneath the last row (or onto an empty list) never reached
SharpTreeNode.InternalDrop.
2. The middle 50% of a row produces a DropPlace.Inside target on the
row's own node. Most concrete SharpTreeNodes inherit the base CanDrop
(returns false), so a literal "drop a .dll onto an assembly row"
refused even though AssemblyListTreeNode happily accepts that payload.
For (1), fall back to (Root, Children.Count, DropPlace.Inside) when no
row is hit. For (2), introduce PickAcceptingTarget which retries with
the empty-space (root) target when the initial CanDrop is false. Both
OnDragOver and OnDrop go through the same picker so the cursor and the
actual drop agree on the outcome. The retry skips when the initial
target already IS the root, so a real refusal still surfaces as "no".
The marker adorner stays hidden for empty-space drops because the
place is always Inside (Item is null for that case); the existing
DropPlace.Inside early return covers it.
DropTarget, DropPlace, and the two new helpers are internal-visible to
the ILSpy.Tests project for the unit tests that assert the fallback
chain.

OnTextInput drives incremental prefix search over the visible (flattened) nodes with a 1s idle reset -- a fresh keystroke advances past the current row, a growing prefix refines forward. A regression test confirms the payoff of the ListBox base: SelectionMode.Multiple extends AND shrinks a shift-range from the anchor (Shift+Down x2 then Shift+Up -> A,B), so the migrated control needs none of the ProDataGrid reflection workaround.
First increment of the from-scratch Avalonia tree control that will replace the ProDataGrid hierarchical usage. SharpTreeView : ListBox binds the cross-platform TreeFlattener (an IList + INotifyCollectionChanged of visible SharpTreeNodes) straight as ItemsSource, so the ListBox virtualizes it and provides anchor-based extend/shrink selection natively -- no HierarchicalNode wrapper, no model<->grid sync layer. Includes Root/ShowRoot/ShowLines props, Reload/flattener wiring, deselect-on-hide, selection->node.IsSelected, FocusNode/ScrollIntoNodeView/HandleExpanding, container overrides, and the tree keyboard gestures (Left/Right, numpad +/-/*, Enter/Space activate). SharpTreeViewItem : ListBoxItem (double-click expand), an IPlatformRoutedEventArgs adapter, an indent converter, and a ControlTheme (chevron expander + indent + icon + text) wired into App.axaml. The control is additive and not yet wired to any pane. Smoke tests prove the core: flatten, virtualize, expand/collapse row-count updates, and selection sync.
