New double-tag focus

[RiverLeaf]

PRESENT 3126 active tag is pleasant stipple underline focus.
Great, but what parent?
REQUEST v4 parent is stipple double-underline and active child is single underline.
IF active is html, then single stipple underline.

So, what you’re requesting is to highlight not just the brackets or tags for the current scope, but also those of the parent scope e.g. with a different underline style?

I went deeper with more careful consideration. This thread is for ST3. For ST4:

How to distinguish active hierarchies for tag and tab

Situation: HTML, Plaintext and Markdown editing text blocks, the active tag is not always underlined. What would be nice and standard is active tag gets a special background color. Taking it to a professional coding environment, tmTheme file could include diminishing color-tone emphasis for active grandchild-child-parent-grandparent tags. Say the guide is white or black (light and dark), then code-line Guide highlighting stands out with diminishing shading as one's eyes move from active grandch…

Whatever version, ST has not paid enough attention to code cascade hierarchies’ visible presentation. Stiple underline is a default behavior but poorly implemented for ST3126.

For example (this thread blocking code, so just a description), enter text in a p tag and no tag underline. Cursor column 1 left of p tag inside section tag inside article tag, article tag underline.
Same page, inside section and article, just right of p tag, p underline.

The feature is rabid. Closing tags with simple “</” works every time, almost. Whatever version, ST needs to pay more attention to tag hierarchies.
