The ? icon means it cannot find the bmp under that name. Are you sure it's in the directory you think it is? it should be in ...\plugins\Config\snippets-toolbar-icon.bmp, based on your screenshot.

What version of Notepad++ are you using? Plugin DLLs have never gone in AppData\Roaming\Notepad++\plugins\config that I can remember (that's the directory for their config files, not their DLLs), and they haven't gone in AppData\Roaming\Notepad++\plugins\ for at least 5 years -- I know for sure that with v7.6-7.6.3 in 2018, when they reorganized the structure, it was made so plugin DLLs could only go in <install_dir>\plugins\<PluginName>\, and I thought that even before that, it was the default of...

SQL Highlighting: does not handle nested comments
So far, ... you haven't defined the behavior you do want. In my example above, putting the caret at the 3and then doing ParaUp should take you to the line labled 3 (which is internally line 2). If the caret were already at the beginning of that line (before the e), then it would still take you to the beginning of the line labeled 1. This could be accomplished by changing // In the code, lines are numbered from 0, not 1 line--; to // In the code, lines are numbered from 0, not 1 if(current_caret_column==0)...
Interestingly, I would say that your analogy works better for my argument. If you have the phrase the word, and the caret is immediately before the w, then the caret is at the beginning of the word word, and so a Ctrl+Left should take you to the; but if the caret is between the w and the o, then the caret is not at the beginning of the word word, so Ctrl+Left should take you to the start of word. Similarly, the digit 3 in my example paragraph is not at the beginning of the paragraph: it's well into...
My point is that ParaUp behaves differently depending on where in the paragraph you are in. If you are on the second (physical) line or beyond of a given paragraph, then ParaUp will take you to the start of that paragraph. If you are on the first (physical) line of a given paragraph, then ParaUp will take you to the start of the previous paragraph.
