I haven't found any existing options yet for this. Served html files do not seem to live on my filesystem....
So if it is up to a change in the Aida64 program.... This is my pitch on how to implement it:
To the preferences -> LCD --> RemoteSensor panel I would like to add:
4 textbox to reference to a file containing additional HTML code (or a textbox to paste html into)
1) HTML Head additions - adds to end of head section (to add JS file include, overwrite title, etc.)
2) HTML Body prefix - adds to beginning of body sections
3) HTML Body Postfix - adds to end of body section (so all Aida64 sensor items are between 2 and 3)
4) CSS additions (adds to end of CSS, so existing items can be overwritten that way)
a 5th textbox may contain a media path for referenced images/sounds/files.
Let me know how you think about this! To my opinion this can greatly help creativity with the remote sensor panel! I have already some great ideas that I love to work out.
