I'm wondering if the developers have considered adding the option to script mouse events, receive information about the object being clicked (full data, which will include selection status and other stuff a developer might want to tinker with). I think this would be a nice addition to DOpus, which I have proposed a while ago.
About 8 months ago I was interested in purchasing DOpus, but I ran across an issue which I found to be a deal breaker ( Power Mode Left Click to only move caret? ). I couldn't emulate a behavior I find important in my current file manager (Total Commander). I invested quite a bit of effort in adapting to DOpus and I'm still interested in it 
.
The script I'd like to be able to write would look like this:
//Ignore all other left click behavior: do not toggle selection, however, *do* move the caret to the location of the left click.
@script jscript
function OnMouseClick(data)
{
if (data.leftClick)
{
Item.focused = true; //I do not know the command for this so I'm writing in "pseudocode".
if (Item.selected) data.func.command.RunCommand("rename inline");
}
return;
}
.
