Dasoul for what it's worth I switched from Mobirise to Bootstrap Studio a couple months ago and I have been more than pleased with the results. Everything I was doing with M I can do in BSS plus a lot more.
To me it boils down to this between the 2 programs. With M you don't need to know much about coding or Bootstrap whereas with BSS you do if you want to get the most out of the program.
Regarding your comments that you haven't found a way to change the text alignment of a heading, select a heading then you'll find the options to change its alignment in the options panel.
Same thing with resizing images including logos, just turn on the responsive option for each image.
I hope you'll like Bootstrap Studio, I love it, and I also purchased the lifetime version before I ever saw the program.
Good Luck and welcome aboard.
