### 4/5 — Gutes Programm mit kleiner Einschränkung

*2026-05-31*

Ich bin von dem Programm sehr begeistert. Hat man sich an die Bedienung gewöhnt kann man damit zügig arbeiten. Auch die Codeerstellung ist sehr hilfsreich. Eine kleine Einschränkung gibt es meiner Meinung nach: Die grafische Darstellung des Struktogrammes geht sehr schnell in die Breite, wenn mehrere Decisions ineinander verschachtelt sind. Die App versucht immer alle Blöcke gleich breit zu halten, wodurch dann schnell die Übersicht etwas verloren geht.
Das ist aber das einzige Manko. Ich arbeite sehr gerne mit der App.

## Version history (last 5 releases)

### 1.5.1 — 2026-05-16

• Improved canvas readability and overall visual design
• Refined editor layout and usability
• Updated the do-while loop labeling for better consistency with common programming terminology
• General improvements and optimizations

### 1.5 Simulator — 2026-05-08

* Novo simulador para execução passo a passo dos algoritmos (semelhante a depuração)
* Melhorias na geração de código
* Interface de utilizador redesenhada e otimizada

### 1.4.2 — 2026-05-07

Melhoria na edição das estruturas de entrada, saída e controlo.

Os prefixos de entrada e saída estão agora integrados diretamente no editor e já não podem ser eliminados acidentalmente. As condições para if, while, until e switch passam agora a ser editadas com designações fixas e claras, enquanto o estruturagrama continua a apresentar o texto completo e legível. A geração de código para JavaScript e Python também foi adaptada a estas novas melhorias do editor.

### 1.4.1 Speichermenü — 2026-05-05

Added a save warning when closing unsaved diagrams.

### 1.4 — 2026-04-30

Added support for arrays
Improved for loops
Better code generation output
Bug fixes and stability improvements
