Might be a legit reason to report to the dev.
It might be not tha legit to say, I know, but: it still sounds to me like you did not understand that Melda-Plugins have a deep eco system with a whole framework in the backend. This might lead to funny help texts, but it is easier in the plugin itself: simply press F1 when hovering over a control. No need to cycle through manual pages anymore, since the help immediately appears on the screen.
Overlapping textboxes: with great flexibility comes such things. Yes one might not like it, but in the end I could not even think of better ways to giving the user so many options, while offering a ... "better UI" at the same time. But maybe some user ideas and dev ideas might change some things in the Melda tools and things will start to attract other "non-Melda"-users as well at some point in the future.
