-1. fix vertical lines to small to be seen: in some cases (e.g. rect waveform in @mock_upstreamer.py) the vertical lines are to thin to be visible (sometime they glitch in and out of existence):
-   1. the antialisaing strategy with phosphore effect should be applied with more stregth
-   2. the lines should be more tick
-   3. the sample points should be bigger
-2. ~~relative timing~~ **done**: `--relative-time`; see README and SPECS.md for the measured history cost.
-   - in order to avoid problem with time jitter user can decide to go in relative time mode
-   - in this mode absolute signal time is only use for export
-   - the plot time depends just on signal sample rate and frame number, e.g.:
-     - user is acquiring a signal with 1MSps and 100_000 samples per udp frame
-     - last frame as number <N> and previous <N-2> in this case a 100_000 indexes must be skipped
-     - time is simply: `((<N_frame> - <N_last>) * <n_samples_per_frame> - <sample_index>) / <sample rate>` (or something like that)
-3. named configurations: in order to have multiples configurations for the same sources configuration can also have comments
-4. optional udp frame storage for debugging of strange behaviours (store last <N>, default = 1000, udp packets binary content on disk for forensic analyss)
-5. open exported binary waveforms to view/analyse, in the source selection dialog there should be the option to open exported waveform (maybe a tab with latest opened file and option to open new ones?)
-6. imporve right click menu on the plots:
-   - use same compact style of main menu
-   - add a [remove signal] entry that open a submenu to delete signasl
-7. in layout edit mode add the option to drag plot border to resize them
-8. add option to automatic save the last <N> triggered acquisitions in a cache folder and let the user replay them
-   - a collapsable pane on the left with the list of the last <N> acqusition with duration number of signals etc
-   - user select one and immidiatly open it
-   - this option would only be available in trigger mode
-9. preferences dialog:
-   - user can choose evnt cache directory (default <home>/.cache/udpscope/<source>/events/)
-   - maximum number of events to cache
-   - disable completly the events storage option
-   - enable/disable relative time mode
-   - interface dark/light/auto color
-   - defaults
-   - other parameters

+  3.  the sample points should be bigger
+- [x] (2) ~~relative timing~~ **done**: `--relative-time`; see README and SPECS.md for the measured history cost.

+- [x] (3) ~~named configurations~~ **done**: one directory per source holding `<name>.toml` per configuration plus `active`; a configuration carries a note and the startup settings (`buffer_mb`, `relative_time`, `capture_packets`); the chooser lists them and the menu's _Configurations…_ opens/saves/deletes them.
+- [x] (4) ~~optional udp frame storage for debugging of strange behaviours~~ **done**: `--capture-packets N`; see README and the design note in `docs/superpowers/specs/` for the ring file, the popover toggle and `tools/capture_to_pcap.py`.
+- [x] (5) ~~open exported binary waveforms to view/analyse~~ **done**: `--open FILE` and the chooser's **Waveforms** page (the files opened before, newest first, plus *Open…*); the `.npy`'s dtype names the columns, so a load restores the signals, the samples and the axis the export had, and every instrument works on it — see README and `docs/claude/invariants-data-path.md`.
+- [x] (6) ~~imporve right click menu on the plots~~ **done**: the plot's context menu uses the main menu's row style (`menu_button` + `.udpscope-menu`, asserted by `UDPSCOPE_PROBE_ROWMENU_MS`: uniform `label_x=26`, `h=18`, the shortcut flush right), and deleting a signal is a **Remove signal** submenu listing that plot's traces plus _All traces on this plot_.
+- [ ] (7) in layout edit mode add the option to drag plot border to resize them
+- [x] (8) ~~add option to automatic save the last <N> triggered acquisitions in a cache folder and let the user replay them~~ **done**: every latch is written to `<cache>/<source>/events/` as a `.npy` (the export format), a `.txt` sidecar and a `.bmp` preview drawn from the samples; the **events pane** (revealed with trigger mode, switchable) lists them with time, duration, signals and rate, shows the preview, replays one through the `--open` loader and has *Live* to go back -- see README and `docs/claude/invariants-trigger-and-pinning.md`.
