• issues with install sequence that needs to be address I sent over a fix PR
• https://github.com/dimitribarbot/sd-webui-live-portrait/pull/2

• output directory not configurable you should add a setting either under Paths for saving or your own Live Portrait settings to allow the use the change the output dir like what is customary for webui as far as I can see you have it hardcoded to data_path/outputs/live-portrait/datetime.date.today()

• issue access to external resource see online tags

those icons are unnecessary and access to external services unnecessary as in those who install this extra should have already visited your GitHub web page and so understand what they are installing and so I have already visited the original web page so the icons serves little purpose and is taking up valuable web page space reducing usability

if you really want those icons put them in your readme.md

Hi @w-e-w,

Thank you for your feedback and contribution!

I've answered your first point in your PR.

As for your two other suggestions, I've made modifications in the extension repository to take them into account. You can check them if you update your LivePortrait extension to the latest version.

Please let me know if you think I should make any further changes.
