Don't want the zoning window area getting to big and potentially obscuring stuff. Kinda ruins the chat while zoning feature
Also don't want the prog bar covering the Exit button.
Yah more bag styles will be released, though 2 across isn't quite as practicle with upwards of 36 slots. 18 tall could be an issue, thats about 600 pixels high at 75% scale, 820 at 100%.
A recent test had Dynamic bags working with stay-put feature, so I'll probably release a couple unconventional fills. DynamicBags can completely rearange slots and window sizes for each bag depending on its slot count. So I'll probably do one that fills down 12, then balances 2 columns till 24, then balances 3 columns till 36. 12 slots would be a single column, 14 slots would be 2x7, 30 would be 3x10 for example.
Basic predictable fills are easy to do in Notepad. Just take an existing bag file of the scale you like and tweak it. Sizer properties on the page object set window size for the matching slot count. Other than that, you just gotta set the slot locations.
