I'm not sure what version precisely, but the version which kept all settings on the left-side panel. The floating Menus you implemented are almost always on the way, they also appear with a little pointing arrow confusing users, because they are pointing to the wrong page element.
You DO NOT TEST YOUR EXTENSION on the 4K screens and seem to have no idea how messy SPPB is when working on the pages.
Keeping most of the properties on the side panel is more convenient and also will cause less issues to you.
The only features we need on the page are icons to allow re-arrange objects (elements) layout. Move something above OR below, to the left or right etc. I also see the COPY feature but not CUT - why ?
WP Elementor has a nice feature allowing quickly Copy/Paste style of one element into another. THIS IS A MUST ! and I do not understand why this is not implemented. IT IS CRUCIAL !
If I have 20 Elements (blocks) on the page and want to change the text style (ie. color) I have to do it 20 times !!!!
Unless I am missing something THIS IS ABSOLUTELY INSANE !
