Here is a work-around I am currently using:
Open your dynalist main document in Chrome(works for other browsers too). In chrome, menu>more tools>Create desktop shortcut with ‘open as window’ enabled.
Go to desktop, copy the shortcut file. Then paste it again and again till you have 4 or 5 copies(as many as you need). Copy them all and paste them in your windows startup folder(win+r and type shell:startup, press enter). Now they launch on startup, you can let them sit in the background. Use them as needed but don’t close them.
The delay in loading dynalist when you open a new browser window/tab(upto 9 seconds for me). Once that’s loaded, you can switch between pages instantly as long as the page stays in memory. This workaround pre-loads several browser windows so you jump in and work on several documents side-by-side without waiting for the contents to load. Better for workflow.
I am using ‘create shortcut-open as window’ so the interface has less distractions and resembles the desktop app instead of chrome.
It does, however clutter up the taskbar a bit.
