Yes. Adobe is moving all their apps towards the UXP. If you are wondering if the plugin will work on your computer, please install the Free version first to make sure it does.

Sadly Adobe is retiring JSX functionality overall. As far as I know there's no timeline yet and that means it might be years until JSX stops working at all, but running these scripts is already not supported in UXP plugins. Custom Panel happens to be a UXP plugin too and this is the direction Adobe is going. Adobe warned developers about potential workaround, because it might stop working on any of upcoming Photoshop updates (if it still does). A lot of users have been using JSX scripts for years and transition to UXP is a bit painful, but it's worth rewriting them at the end if they are used daily. I really understand the need, but I'm not willing to implement something, that might stop working in a couple of weeks (or even years - no timeline). Having said that, you could try another workaround (if it still works):

• Create an action, that executes your JSX script (lets name it "Action 1")
• Create an action, that plays previously created "Action 1" (lets name it "Action 2")
• Assign "Action 2" to your button in Custom Panel

Basically you should assign an action, which plays another action, which has a JSX script in it. Note, that this also might stop working at any point. BTW, Adobe introduced UXP Scripting and they encourage everyone to migrate from JSX to PSJS. I really hope this explains why JSX scripts are not working in UXP plugins and I hope you will understand the decision behind a lack of the feature.

Unfortunately, drag'n'drop is still not supported in UXP plugins. Adobe is aware of this and they promissed to look into it. As soon as it is available, I will get to implementing it.

Direct shortcut assignment is not allowed by Adobe for 3rd party plugins. However, on a Pro version there is an option to record an action and assign a shortcut to show a space popup (a pie-menu closest possible alternative) where you can have keyboard shortcuts for every button. Unfortunately these shortcuts don't work on a panel directly because of the reasons mentioned earlier, but you can also record an action for each button and assign a shortcut to that action. Action recording and keyboard shortcuts are available only on a Pro version.

Unfortunately, no. At least not yet. I will evaluate at some point how feasable this would be. Uploading and using a custom icon with unknown dimensions might cause UI to break. Also not all features of SVG are supported by Adobe - if the uploaded icon would have any of these features, it might seem, that plugin is broken and something does not work.

Currently plugin requires Ps v25.2.0, but as Adobe adds new features, this might change, if plugin would require some of these new features to work.

Yes, you will be provided with a CCX file download link, if you get a license via a LemonSqueezy store or choose this option here on the page. If you choose the Adobe Marketplace option, this will require Adobe Creative Cloud Desktop app to install the plugin.

If you installed a plugin via Adobe Marketplace, Adobe handles the validation process via the Creative Cloud Desktop app and this requires internet connection on every app startup.

If you use a downloaded version, it will require a connection to validate the license on a first use. Then you will have a 3 day backoff - only after 3 days without the connection will prevent you from using the plugin. If you have internet connection and use the plugin, it will extend the three day period, so you would not need to validate your license every 3 days.

If you installed a plugin via Adobe Marketplace, you have the same limitations as Photoshop app - activate on 2 devices, but use only on one at a time (ref.)

If you use the downloaded CCX version, you can use it on one computer at a time. When you try to activate on a 2nd computer, you will be asked to remove the previous activation.

Plugins main language is English. Currently also Italian language is supported.

By default selected language is the same as Photoshop, if supported by the plugin, but you may also override by manually choosing it in the plugin settings.

Plugin is provided to use as is with no warranties. There is no tracking or any other data collection, apart from the data required for license validation if you have the downloaded version.

Any version you acquire, will get support and updates while the license is valid. This means, that Free, Lite and Basic versions have a lifetime support and updates. However Plus and Pro support will always have a priority.
