Throttle v0.2.0

Throttle can now look the way you want it. This release adds a Themes menu with 37 colour palettes, a Customise window for shape and size, a View menu for what is on screen, a filter box above the process table, and a tray menu that switches your rules on and off. Nothing changes until you pick something: the stock look is exactly what you had before.

Themes

Open the Themes menu and click a palette. The menu stays open, so you can click through them and watch the app change. Surprise me picks one for you.

Have a favourite that is not in the list? File > Import theme opens a file picker. Point it at the colour theme file inside any editor theme extension and it appears under Themes > Imported.

Customise

Themes > Customise opens a small window with the knobs that are not colours:

• Corners: square, subtle, round or pill.
• Density: compact, normal or spacious rows.
• Scale: 80 to 150 percent. Ctrl + and Ctrl - do the same thing.
• Font: the default or the monospace one, plus monospace numbers on their own.
• Details: shadows, table stripes, button frames.
• Accents: your own colours for download, upload and blocked. The tray icon follows them.

View

• Show or hide each table column.
• Plot options: filled area, line width, and how much history the header plot keeps (1 to 10 minutes).
• Always on top, and a compact mode that hides the header plot.

Also added

• Filter box above the table. Type part of a name to narrow the list, or press Ctrl+F to jump to it. The Active chip next to it hides every process that is not moving data right now.
• Plot navigation: scroll to zoom the time axis, drag to pan, double click to reset. Right click a plot for Reset view and the plot options. The rate axis now reads in KB/s and MB/s, in 1, 2, 5 steps.
• Rules can be switched off without deleting them, from the right-click menu or from the tray menu, which lists every rule with a check mark. A switched off rule shows as "Off" in the Rule column. Setting a new limit or blocking turns it back on.
• Tray tooltip shows the current download and upload totals, so you can glance at the tray without opening the window.
• Folder button next to the process name in the detail panel opens the folder its executable lives in.
• Remembered layout: window size and position, panel sizes, column widths, sort order and the Active chip all come back the way you left them.
• Buy me a coffee link in the Help menu and the About dialog.

Changed

• The window opens at 1280 by 800 on first run (was 1100 by 720).

Fixed

• The limit field in the Set limit dialogs only takes a number now. Letters and other characters disappear as you type instead of producing an error on Apply, and the field is the same height as the unit box beside it.
• Settings and rules files that an editor had saved with a byte order mark were read as empty and reset to defaults. They now load.

Notes

• Everything here is opt in. A fresh install or an upgrade looks and behaves like 0.1.3 until you change something.
• The palette colours come from open source themes under the MIT licence. Attributions are under Help > Third party notices.
• The in-app update replaces throttle.exe only. The bundled WinDivert files are unchanged in this release.

Internal

• New modules: theme (palettes and import), appearance (Customise), plot (shared plot builder, grid and navigation), tray (menu, tooltip, icon) and units (formatting). Table and panel sizes are persisted in the settings.
• Rules gained a disabled flag. Older rules files load as active. The engine skips disabled rules and releases their shaping buckets at once.
• New dependencies: rfd for the file picker, and eframe's persistence feature for the window geometry.

Thanks

Thanks to @Amel-Okicic for proposing themes and UI ideas in #9, which started the Themes menu.
