Indent and Outdent button pupose is not clear

[MCGods]

Version

v1.30

Test Environment

Windows 10, Firefox & Chrome

Current Behavior

When hovering over the buttons I see 'Indent' and at first thought I think the text will indent however this button is intended for lists.

Expected Behavior

The purpose of the button should be clear to the user.
Eg. On hover I expect the tooltip to say 'Indent list'.
The task button by default should not separate lists and indentation buttons (before the lists?).

To Consider

It should be taken into consideration that the indent button, indents the line in md mode and hence creates the codeblock.

Ran into this same issue with our testing. People were trying to indent text
