<p>
The rgthree-comfy ${this.type.replace("(rgthree)", "")} node allows you to add a floating
label to your workflow.
</p>
<p>
The text shown is the "Title" of the node and you can adjust the the font size, font family,
font color, text alignment as well as a background color, padding, and background border
radius from the node's properties. You can double-click the node to open the properties
panel.
<p>
<ul>
<li>
<p>
<strong>Pro tip #1:</strong> You can add multiline text from the properties panel
<i>(because ComfyUI let's you shift + enter there, only)</i>.
</p>
</li>
<li>
<p>
<strong>Pro tip #2:</strong> You can use ComfyUI's native "pin" option in the
right-click menu to make the label stick to the workflow and clicks to "go through".
You can right-click at any time to unpin.
</p>
</li>
<li>
<p>
<strong>Pro tip #3:</strong> Color values are hexidecimal strings, like "#FFFFFF" for
white, or "#660000" for dark red. You can supply a 7th & 8th value (or 5th if using
shorthand) to create a transluscent color. For instance, "#FFFFFF88" is semi-transparent
white.
</p>
