First of all, thanks a lot for your in-depth reply! We will definitely take into account all of your input!
Regarding the areas you have mentioned, we will add some comments that we hope you find useful:
You can find some helpful tips in our Grammar Hints section (ser/estar, por/para, prepositions, pronouns...). Soon you will find more information available in there as there are other hints we are in the process of creating (the passive voice, subjunctive mood and tenses, pronominal verbs, etc).
As for the idiomatic expressions you may find on the cards, we would like to encourage you to try to understand them in their specific contexts, taking their meaning from the usage/literal translations provided. It is not necessary to focus all of your attention on them at this point, as they will distract you from acquiring the vocabulary and structures that you will need to "decode" them in the future.
You might have not realised, but the fact that you are able to point out such specific areas of language makes you already an advanced learner! Don't worry too much, just keep learning and practising at you own pace: comprehension and mastery will come naturally in time :-D
We're creating a lot of new content both on Lingvist and The Forum. Stay tuned and remember that you can count on us to help you along your language-learning journey!
