Problem Description / Use Case

There's currently no way to set up a tooltip on buttons (both from tray and ctx.action). Modification via js script is also not possible as we can't assign classNames on buttons (at least on ctx.action). It would be a lot easier and cleaner if the API adds supports on it rather than inserting our own scripts just to add a tooltip.

Proposed Solution

additional traybutton and uiObject prop named tooltipText

// example for tray
$ui.Tray.button: (label: string, props?: ({
    onClick?: string | undefined;
    intent?: $ui.Intent | undefined;
    tooltipText?: string | undefined; // Text that gets shown when hovering over the button
    disabled?: boolean;
    loading?: boolean;
    size?: "xs" | "sm" | "md" | "lg";
} & $ui.ComponentProps) | undefined) => void (+1 overload)

// example for anime page
 $ui.Action.newAnimePageButton(props: {
    label: string;
    intent?: $ui.Intent | undefined;
    tooltipText?: string | undefined; // Text that gets shown when hovering over the button
    disabled?: boolean | undefined; // a followup on support for `setDisabled()`
    style?: Record<string, string>;
}): $ui.ActionObject<{
    media: $app.AL_BaseAnime;
}>

also, request to add newMangaPageDropdownItem (if possible) for parity with ctx.action.newAnimePageDropdownItem
