Newbie here. I am still looking at adopting B4X into my environment.
In my opinion the one 'tool' that would be most helpful (for me) would having the ability to print form layouts for reference. The print out would be for each page showing the control name. If a table is on the page. It would print column details. So if you had 4 pages on a form. The printout would have 4 pages.
In my 35+ years of programming - I have looked at numerous development systems and they ALL lack this feature. The closest I have seen is a tool called DR Explain. However it will not show hidden controls and table details (like hidden columns). Personally it seems like I spend most time documenting form layouts vs database layout, and actual code.
Just my thoughts
