Add equivalent of "hover" for touch displays

What is the current behaviour and why should it be changed?

On desktop builds, hovering the mouse over the channel user displays their profile details in a tool tip:

As no "hover" action is available for touch displays (e.g. Android), this feature is unavailable.

Describe possible approaches

A single tap or, probably better, long-hold could be used to display tool tips in general. (Long-hold would avoid misinterpretation of single tap on a checkbox or menu, etc.)

I'm guessing touch screens also are missing right-click "What's this?" support. Possibly that could be implemented as above, with "Show musician profile" as an extra option where applicable.

Other trigger actions could be double tap or two-finger tap. Long-hold is prefered, I think.

Has this feature been discussed and generally agreed?

Only with my partner, who raised it.

まず、チャンネルユーザー向けのデスクトップのホバーツールチップと、右クリック時の「What's this?」の動作を見つけ、次にタッチ入力がどのように処理されているかを調べます。この Issue には合意されたジェスチャーが必要であり、タッチによって関連するツールチップまたはミュージシャンのプロフィールが表示され、コントロール上のタップを誤って解釈しない状態になったら完了とみなします。
