[Request] Regain lost focus upon opening new image

[DavidHale34]

Hello,
I'm having the program as default image viewer and when I manually click on a new image the window of JPEGView doesn't resurface, like it would do on first launch i.e if I already have the program running, clicking on new images doesn't make it pop back up. This often creates a need to manually bring up the window in case it's overshadowed by other applications. Please, implement a way to either refocus or simply terminate and relaunch. It would be a huge QoL improvement, thank you.
