One of my biggest problems with the SmartList in Microsoft Dynamics GP is the size of the two panes. The left hand pane resizes itself when you change the size of SmartList; when maximised it ends up being two fifths of the screen size which seriously cuts down the space for viewing the report.
But, now, help is at hand. Frank Hamelly, a Microsoft Dynamics GP MVP, on GP2themax has posted a modified SmartList window, from Nicole Albertson of Microsoft, which resizes the left pane.
The modified window is loaded in via Customisation Maintenance (Microsoft Dynamics menu ¯ Tools ¯ Customise ¯ Customisation Maintenance) from a .package file and works by keeping the left pane a set size which maximises the pane showing the report data.
Hopefully, the next version of Microsoft Dynamics GP will come with a built in solution to this.
