GridLayout

Lazarus component, to arrange components in a grid: rows, columns, width in columns, height in rows. It looks a bit more compatible to Delphi's [https://docwiki.embarcadero.com/Libraries/Sydney/en/Vcl.ExtCtrls.TGridPanel TGridPanel], though not completely (e.g. some properties are named differently, the control collection is [https://docwiki.embarcadero.com/Libraries/Sydney/en/Vcl.ExtCtrls.TControlItem TControlItem] instead of TGridPanelControl, and the later misses some [https://docwiki.embarcadero.com/Libraries/Sydney/en/Vcl.ExtCtrls.TControlItem_Properties properties] as well).

Com problemas para definir a navegação com formulários e frames da sua aplicação? Cansado de usar TTabControl e TTabItems para compor a UI do seu App mobile ou desktop? A transição SLIDE do TTabControl é legal, mas já está muito batida? Cansado de usar TFrame como classe base para suas views? No FMX até um TEdit pode ser usado como componente agregador, então que tal usar TLayout, ou qualquer outro componente derivado no lugar? Quer mais liberdade para manipular suas listas de views, sem abrir mão de controle? ViewLoader.
