I saw your post in the Questions forum and can see your and Pendrush's needs. I often have multiple IDEs open when I'm coding. Maybe the wish should be that you can only open one instance of a project but still have multiple different projects open?
I am not privileged as many here with bigger screen and many rams. My machine gets hots up and slows down at times, so I have to close some of the running programs. But I have to keep open browser, text editor and B4A ide along with some must have tools in memory.
That's why I requested to have an option for single instance of ide.
Those who can afford are welcome to not use this option in the ide, if and when Erel fulfills my wish.
Sometimes I will have multiple projects open (comparing code etc) and will inadvertently reopen my main project again / again (via desktop shortcuts)
After some code changes and realizing the situation I do experience 'Heart flutters'
It would be good to at least receive warning the project is already opened in the IDE.
Doesn't solve the wish by the OP, but is a nice help for those who do want multiple IDEs open:
I made the small investment in Groupy by Stardock (5.99€) and haven't regretted it since. It automatically groups multiple instances of a window together with easy to access tabs. This way, all by B4J IDEs are nicely grouped together, just like my explorer windows and Web browsers.
Together with FancyZones (part of the free PowerToys tool by Microsoft to create complex window layouts and quickly position windows into those layouts), my desktop is a lot less cluttered

ok... that does look interesting ! I'm in . I was a big fan of Stardock 'Fences' prior to my latest PC build (always try to rethink / change habits with new builds)

which made Erel make a better PreoptimizedCLV
So I have solved my problem of closing the earlier opend B4A ide quickly, by just pressing ESC key, using my Esc Close

@AnandGupta .. There is a small app that restricts multiple instances of apps running. Have tested it and it works.
Although it does not achieve you exact wish , you might find it useful.
