Need help improve MountIso dolphin plugin

[Kwon-Young Choi]

Hello,

I was very excited today to find out that the MountIso plugin I
contributed to dolphin was officially released today:
https://kde.org/announcements/releases/2020-08-apps-update/

However, there is still some work to do to improve the code and user
experience of the plugin.
I made some merge requests on gitlab:

* https://invent.kde.org/sdk/dolphin-plugins/-/merge_requests/8
* https://invent.kde.org/sdk/dolphin-plugins/-/merge_requests/2
* https://invent.kde.org/frameworks/solid/-/merge_requests/10

But they still need to be reviewed and improved.
I would be very grateful if anybody could look at them and give some
feedback so I know what I should do next.

Thanks for your help!

Kwon-Young Choi
