Rethink the dataset centric, drag and drop approach to GUI design. Support alternative approaches to application design such as MGM/MVC/MVP. Add VCL and tooling support for these practices.

The Delphi compiler could generate more efficient assembly code if it would do some simple optimizations. Thing to look for : Make better use of the fact that lots of operations already set flags (so a comparison can be avoided). Improve in the register-allocation (don't do "MOV eax, ebx; SHL eax, cx" when eax will be re-used anyway - SHL ebx itself then). Don't emit opcodes that have already been emitted and will give the same result - try to re-use the previous result instead. Etc, etc.

Rich Internet Application development with Delphi.
like Adobe Air
like JavaFX
like MS Silverlight

Include an out of the box profiler with resource and memory debugging.

Please, add support for loading/using minidumps. Either in MS's format or invent your own (provide a library to create them).

This is invaluable for debugging application crashes.

Include in-the-box support for the PostgreSQL database.

Sometimes we need to show various things when a form is shown, like another form, starting a progressbar, the form's OnCreate and OnShow just don't do the work as both are fired before the form is shown, Instead of hacking our way out or using the OnActivate event, an OnAfterShow event would be perfect

Android is a new market place. We want to develope android applications on delphi (pascal syntax).

To make Visual Studio interop debugging possible ...

If a control is disabled (Enable = False) then the mouseover hint is not shown. Add new propertys
DisabledHint and ShowDisabledHint .

I see this as a right click on form, toggle Lock Design, and the form (just that one) could or could not be edited (GUI elements can not be moved, components can not be added, etc...)

Dependency Injection is getting to be so commonplace -- and so powerful and useful -- that it should become part of the Delphi RTL.

The product is really expensive, lower the price tag so new programmers can look at it and see the power of Delphi by themselves. I really love this product but with the price I'm stucked to 2005 version.

A tool or SDK to make installation of third-party components and packages automated and very easy.

DelphiPI did something that makes it a little easier.

Every thing has been said in the following link. http://vcldeveloper.com/news/firemonkey-and-support-for-bi-directional-text/

As stated in the link there is no consistency even in the VCL for how BIDI is handled.

If Firemonkey supported BIDI across the board the VCL issues would not matter for me anymore.

Take advantage of multiple cores by compiling multiple separate units simultaneously.

More facilities to create Delphi plugins including complete Editors

Use Delphi parser to generate an abstract syntax tree that can be hooked into. The visitor pattern could be used it iterate over the tree and produce various delphi related tools.
Maybe a design time version of this could be created in the IDE that allows for a RAD approach to tooling.

With Windows 7 not being shipped with IE in Europe; one will quickly need choice for embedding a webbrowser inside a delphi App. IE base only won't cut it!

In the forms designer, CTRL-Z should undo the last selection, move, resize, or change in property editor. Of course, unlimited undos would be even better.
