New in the SumatraPDF [pre-release builds](https://www.sumatrapdfreader.org/prerelease):

## Tab colors

**Set Tab Color** (`CmdSetTabColor`, on a tab's right-click menu) gives a document's tab a custom color ([#2725](https://github.com/sumatrapdfreader/sumatrapdf/issues/2725)).

## Search box on the home page

The home page has a search box above the thumbnails that filters recently opened files by name, with the matching part highlighted. `Ctrl + F` focuses it, and `Esc` clears it.

## Chrome-like tab closing, context menu highlight, find tweak

When you close tabs with the mouse, the remaining tabs keep their size while the mouse is over the tab bar, so you can close many tabs quickly, like in Chrome ([#601](https://github.com/sumatrapdfreader/sumatrapdf/issues/601)). Right-clicking highlights the page element (image, link, ...) that the menu applies to. `Ctrl + F` no longer starts searching right away. Press Enter or F3 to search ([#5312](https://github.com/sumatrapdfreader/sumatrapdf/issues/5312)).

![With 13 tabs open, Dates.pdf is activated and its close button clicked four times: the tabs keep their width so each click closes the next tab that slides under the mouse, and they widen once the mouse leaves the tab bar; then a right-click on a picture outlines it in blue while the context menu is open](https://youtu.be/hhRHyIG13ys)
